Purchase the necessary primary wire from a local supplier. Refer to the above table for the proper size. The wire must meet the following specifications, unless otherwise specified on the harness wire label:

• Copper
• Stranded
• 60V
• Thin-wall PVC insulation (SAE TWP type or equivalent)

Follow the guidelines below when repairing the electrical harness of a Tesla vehicle:

1. High Voltage (HV) circuits are not repairable. Replace the entire wiring harness if there is damage to any of these wires.
2. Wires or circuits within the ancillary bay are not repairable. For Model S (2012-2020), Model X (2015-2020), (all), Model Y (all), or , replace the affected wiring harness if there is damage to any of these wires. For Model S (2021+) or Model X (2021+), if there is damage to any of the wires or circuits within the ancillary the entire HV Battery Pack must be replaced.
3. Wires marked with a ++ sign in the circuit diagram cannot have deviations, have continuity checked manually, be repinned, be spliced, or be reworked.
4. The items listed below are repairable only by a Tesla Service Center, Regional Technical Specialist (RTS), or Field Technical Specialist (FTS). Contact Tesla Collision Repair for guidance if repairs are needed on of the following:
   • Safety-related chassis circuits, such as stability control, ABS, or parking brake
   • Powertrain circuits, such as accelerator pedal signal, brake pedal signal, wheel speed sensors and motor encoder
   • Driver Assistance safety circuits, such as parking sensors, radar assembly, cameras (forward-facing, rear-view, b-pillar, or side repeater)
   • Supplemental restraint system (SRS) circuits, such as airbag and seatbelt
   • Airbag sensor and seat sensor
   • High Voltage Interlock Loop (HVIL)
   • Wiring for any CAN or LIN Bus
   • Coaxial cables
   • Any wire sizes not listed in the Supplies section of this document
   • Wires that have damage within 100 mm of a connector
   • Terminals
   • Any wire marked with a + sign on the wire in the circuit diagram; this indicates a safety-critical circuit

     

     Note

     A + sign on the pin name in the circuit diagram indicates positive power. These circuits are repairable by a body shop if they do not have a + sign on the wire in the circuit diagram.

     

   Note

   At this time, terminals can be repaired only by a Service Center.
   CAUTION

   Do not perform a repair if the wire damage is within 100 mm of a connector.
5. If more than 1 wire in a harness needs to be repaired, plan the locations of the repairs and mark each wire with the approximate location of the splice. Avoid placing the splices next to each other to minimize the increase in harness diameter. Stagger the splices as much as possible.

   

6. Do not perform a splice repair in any area that has movement, such as the liftgate, door, or moving part of a seat harness. Replace the affected wiring harness instead.
   CAUTION

   Do not perform a splice repair in any area that has movement, such as the liftgate, door, or moving part of a seat harness. Replace the affected wiring harness instead.
7. When doing a repair to an electrical harness, contact Tesla Collision Repair as described in Contacting Tesla Collision Repair with the information listed below:
   1. Subject: [Vehicle Identification Number (VIN)] Electrical Harness Repair.
   2. Body of the e-mail:
      • Description from the circuit diagram For example, “WPR04-M RD-WT 2.0”

        

      • The circuit that is being repaired. For example, “Windshield wiper slow speed output from body control module to X990”.
      • Type of repair (single splice, double splice, number of wires affected).
      • If known, how the damage was caused.
      • Photographs of the damaged area. Include photos before, during and after the repair. Make sure that a photo that shows the original routing of the wire is included.

Using a single splice to repair a wire shortens the length of the wire segment. A wire can be repaired with a single splice in the following circumstances (if any of these do not apply, refer to Repair Using a Double Splice):

• The damage is to 1 wire in 1 location.
• The length of the damage is less than 10 mm.
• The harness is long and loose enough to be unaffected by the shortening caused by this repair.
• The repair will not put excess strain on the wire where it enters the connector or harness transition.

For the Single Splice Repair procedure steps, refer to the Single Splice Repair Procedure.

A wire should be repaired with 2 splices in either of the following circumstances:

• Damage to 1 wire in 1 location that affects more than 10 mm of the wire.
• Damage to 1 wire in more than 1 location, to be repaired by adding a new section of wire.

For the Double Splice Repair procedure steps, refer to the Double Splice Repair Procedure.
