Overview & Operating Principle
▲

The WIRING HARNESS is an automotive wiring harness assembly — a precisely engineered bundle of insulated copper conductors, shielded data cables, connector housings, and protective conduit that forms the complete electrical interconnection infrastructure for a specific vehicle system or zone, routing power, ground, and signal circuits between control modules, sensors, actuators, and junction boxes in a single pre-terminated, routing-specific assembly that installs as one unit. Unlike individual wires routed separately, a wiring harness integrates all conductors for a functional group — engine management, transmission control, instrument cluster, door, or body — into a single routed assembly whose branching topology, conductor gauges, connector pinouts, and protective sleeve selection are engineered simultaneously for the electromagnetic compatibility, current-carrying capacity, and service environment requirements of the specific vehicle architecture. Each conductor's cross-sectional area is selected for the maximum sustained current of its circuit plus a safety margin; shielded twisted pairs carry differential CAN bus, LIN bus, and analogue sensor signals where electromagnetic interference immunity is critical; high-current circuits for starter motors, alternators, and heating elements use heavy-gauge unshielded conductors with appropriately rated connectors; the complete harness is wrapped in corrugated conduit, braided sleeve, or foam tape at positions where abrasion, heat, or moisture resistance is required. The connector housings at each harness end use application-specific terminal types — male or female, sealed or unsealed, locking or friction-fit — selected for the mating connector on the component being connected, ensuring correct polarity and preventing accidental mis-connection of adjacent identical connectors through colour coding, terminal count, or housing shape differentiation.

This unit — CHERY B113724063 — is manufactured to OEM-equivalent specifications: conductor gauge, insulation material and temperature rating for each circuit, connector housing type and terminal material for each connection point, overall harness routing length and branch positions, shielding specification for data signal conductors, protective sleeve type and position, and circuit count and pinout assignment are matched to the original part. Supplied as a complete pre-terminated harness assembly ready for installation. Available wholesale from 1.24 USD, MOQ 1 pcs, production lead time 30-45 days.

Wiring harnesses fail through insulation chafing where the harness contacts a sharp body edge, a hot surface, or a moving component — the insulation wears through and the bare conductor contacts the body, creating a short circuit that blows a fuse or damages the connected module; through connector terminal corrosion from moisture ingress at unsealed connectors in underbonnet or underbody positions that increases contact resistance, producing voltage drop faults and intermittent component operation; through conductor fatigue fracture at repeated flex points — typically at door-to-pillar transition grommets where the harness flexes thousands of times during normal vehicle use — producing an intermittent open circuit that is extremely difficult to locate without harness replacement; and through rodent damage where insulation is stripped from conductors over a significant harness length, typically in vehicles stored for extended periods.

Symptoms & Diagnostics
▲
Multiple fault codes across several systems stored simultaneously — codes for sensors, actuators, and modules that are not functionally related to each other — appearing after a single event such as a short circuit, rodent damage, or water ingress — a single harness fault that affects the power or ground supply to multiple components simultaneously produces unrelated-appearing fault codes across all affected systems; the common factor — shared supply voltage, shared ground, or shared harness routing — identifies the harness as the fault source rather than multiple simultaneous component failures.
Intermittent fault codes — faults that appear and disappear unpredictably without correlation to temperature, engine load, or driving conditions — on one or more circuits routed through the same harness section — conductor fatigue fracture at a flex point produces an intermittent open circuit that makes contact under some physical positions and loses contact under others; the intermittent nature makes the fault extremely difficult to reproduce during a workshop inspection; wiggling the harness section while monitoring the affected circuit with a scan tool live data view reveals the fault location.
Blown fuse that recurs immediately after replacement — the replacement fuse blows within seconds or minutes of installation — a short circuit in the harness is drawing above the fuse's rated current; locate the short by disconnecting one connector at a time while monitoring the circuit resistance — the section that shows zero ohms to ground when disconnected contains the short; do not install a higher-rated fuse to bypass the repeated blowing — the fuse protects the harness from fire and must be the correct rating.
System fault that is position-sensitive — the affected component or system works when the harness is in one physical position and fails when the harness moves — such as a door module that works with the door open but fails with the door closed — conductor fracture at the door-to-pillar flex grommet is the classic presentation; the conductor makes contact when the flex grommet is at rest position and opens when the door closes and the grommet flexes; confirm by temporarily holding the harness in the fault-free position and confirming the fault does not appear.
Burning smell from the engine bay or passenger compartment — combined with a blown fuse or circuit that will not power up — a short circuit has caused the harness insulation to overheat before the fuse blew; inspect the harness routing visually for discoloured, melted, or charred insulation; a harness with heat damage at any point requires complete replacement — locally repaired harnesses with spliced conductors are not acceptable for high-current circuits where the splice's increased resistance generates heat under sustained current.
Visible damage to the harness exterior — chafed insulation, exposed copper conductors, corroded connector terminals, or missing conduit sections — identified during underbonnet or underbody inspection — any visible insulation breach in a vehicle harness is a fire and reliability risk; even a conductor that is not currently shorting to the body will short under the mechanical stress of engine movement, vibration, and thermal cycling; replace the complete harness assembly rather than attempting an insulation tape repair on a safety-relevant automotive circuit.

Installation Tips
▲
  1. Photograph the complete harness routing — every clip position, grommet location, and conduit path — before removing the old harness — the new harness must follow exactly the same routing to maintain the designed clearances from hot exhaust components, rotating accessories, and moving suspension and steering elements; a harness rerouted even slightly from the OEM path may contact a component it was designed to avoid and will chafe through within months; photograph from multiple angles before disconnecting any connector or removing any clip.
  2. Disconnect the vehicle battery negative terminal before disconnecting any harness connector — many harness connectors carry permanent battery voltage on ignition-off circuits; disconnecting a live connector can arc the terminal, damage the connector housing, or trigger a module fault code that requires scan tool clearing; with the battery disconnected, all connectors can be handled safely; allow 30 seconds after disconnection for capacitors in airbag and other pyrotechnic modules to discharge before working near those circuits.
  3. Transfer all harness routing clips and grommets from the old harness to the new one before installation — harness routing clips are specific to the harness cross-section at each attachment point; the new harness is supplied without the clips from the vehicle; count and remove all clips from the old harness, noting each clip's position for correct installation on the new harness; replace any clip that is cracked or has lost its retention force with a new clip of the correct type.
  4. Inspect all mating connectors on the vehicle side for terminal corrosion and connector housing damage before connecting the new harness — a new harness connected to a corroded vehicle-side terminal immediately begins its service life with a high-resistance contact that causes the fault the harness was replaced to resolve; use electrical contact cleaner and a fine brush to clean each vehicle-side terminal before connecting the new harness; replace any connector housing that is cracked, has deformed terminal cavities, or has missing secondary locks.
  5. Route the new harness through all grommets, clips, and conduit guides in the sequence established by the photographs before securing any clip — confirm the full harness length follows the photographed path and that all branch points are at their correct vehicle positions before pressing any clip into its body hole; a harness routed out of sequence may have insufficient slack at one branch point and excessive slack at another, leading to chafing at the tight point and unsecured conductor loops at the loose point.
  6. Install the new WIRING HARNESS (CHERY B113724063), reconnect the battery, clear all stored fault codes with an OBD-II scanner, and perform a complete functional test of every circuit served by the new harness — activate each connected component individually and confirm correct operation; check for new fault codes after a 10-minute operating cycle confirming no new codes have been set by incorrect connector engagement before returning the vehicle to service.
Tools: camera for routing documentation, OBD-II scanner for fault code clearing and functional testing, electrical contact cleaner for mating connector preparation, new harness routing clips of the correct type, dielectric grease for unsealed connector terminals in underbody or underbonnet positions.
Frequently Asked Questions
▲
When is harness repair with spliced conductors acceptable and when must the complete harness be replaced?
Harness repair with crimped or soldered splices is acceptable only for isolated physical damage — a single chafe point or rodent bite — on low-current signal circuits where the splice is correctly executed with a heat-shrink solder sleeve or a parallel-jaw crimp connector and sealed with adhesive-lined heat shrink; the repaired section must be rerouted away from the original damage source. Complete harness replacement is mandatory when: the fault is an intermittent conductor fracture at a flex grommet where the precise fracture point cannot be located and a splice at the correct position cannot be guaranteed; when the harness carries airbag or pyrotechnic circuits where a splice introduces unacceptable resistance variation; when heat damage has affected the insulation over a significant harness length; or when multiple conductors in the same section are damaged. The guiding principle is that a splice introduces a resistance higher than the original continuous conductor, and on high-current or safety-critical circuits this additional resistance is unacceptable. ok.parts supplies wiring harness assemblies at wholesale MOQ from 1.24 USD per unit.
How can an intermittent harness fault be located efficiently without replacing the complete harness speculatively?
The three-stage isolation procedure for intermittent harness faults is: first, identify the affected circuit precisely from the fault code description and the vehicle wiring diagram — confirm which specific conductor and connector are involved; second, use the wiggle test — connect a multimeter or scan tool live data to the affected circuit and mechanically flex the harness section by section while monitoring the circuit for the intermittent response; the section that reproduces the fault when flexed contains the fracture; third, confirm by isolating that section — disconnect its connectors and test resistance directly; if resistance is normal in all static positions but drops to infinite when the harness is flexed, the fracture is confirmed in that section. This procedure locates the majority of intermittent fractures without full harness replacement and allows an informed decision about whether a targeted splice repair or complete harness replacement is the correct repair for that specific fault location.

Frequently Replaced Together

PartReason for Combined Replacement
Control Module (ECU / TCU / BCM)
Application-specific — module served by the harness		A wiring harness that failed from a short circuit may have exposed the connected control module's input and output driver circuits to voltages above the module's rated limits; MOSFET output drivers in ECUs and BCMs are particularly vulnerable to reverse voltage or overvoltage events from harness short circuits. If the short circuit blew the module's supply fuse, the module itself may have sustained internal damage that produces fault codes or incorrect outputs even after the new harness restores the correct circuit topology. Always perform a full module function test after harness replacement and replace the module if any output channel behaves incorrectly.
Harness Routing Clips and Grommets
Application-specific clip set for the harness position		Harness routing clips that have been in place for the vehicle's service life accumulate UV embrittlement and corrosion that reduces their retention force; clips removed during harness replacement often fracture during extraction. A new harness installed with old, weakened clips will vibrate loose from its routing within a short period and chafe against adjacent components. Replace the complete clip and grommet set simultaneously with the harness to ensure the new harness is correctly secured from its first day of operation.
Fuse and Relay Set
For all circuits served by the replaced harness		Fuses that have been subjected to the sustained overcurrent that caused the harness insulation damage will have had their fuse element heated to near its blow threshold even if they did not blow; a fuse element that has been heat-stressed without blowing has reduced remaining current-handling capacity and will blow prematurely at normal circuit loads. Replace all fuses associated with the damaged harness circuits simultaneously with the new harness to ensure the protection system is operating at its rated values.
