Fitment & installation: Race ECU Harness

  1. Confirm the actual loom length, connector keying, populated pins, wire sizes and supplied relay / fuse hardware.

  2. Use the exact ECU wiring diagram; verify every circuit for continuity and shorts before connecting power.

  3. Route trigger and sensor wiring away from ignition coils, alternators and high-current wiring; provide strain relief and protected power feeds.

05 / Questions about Race

Questions about Race

Will this connect a GEN2 RACE?

This harness serves connector 1 on GEN1 V1 / RACE / PRO. GEN2 uses a different harness; select by ECU generation.

Are EGT connectors part of the main loom?

EGT uses the second loom; confirm its inclusion, thermocouple type and connectors.

Which RACE harness group is this product based on?

ID 871 is the connector-1 harness for GEN1 V1 / RACE / PRO. EGT, electronic throttle and expansion use a separate connector-2 loom.

Is the RACE main loom already terminated for my engine?

The ECU end is terminated; the vehicle end is flying leads. Terminate for the engine and check sensor connectors, relays, fuses and branch lengths.

Can RACE harness REV1 and REV2 be chosen only by length?

Also check harness revision, connector and termination. Equal length does not imply equal pinout or circuits; match each circuit to the ECU.
