Gen5DIY Plug & Play Wiring Harnesses

Plug-and-play wiring harnesses built for the Corvette, using GM sealed connectors that mate directly to your factory plugs. No cutting, no splicing, no pin insertion — the harness goes inline with a connector that is already in the car, and the trim goes back on over it.

The range covers four jobs:

  • Flex fuel power harnesses — draw power from the evaporative solenoid and include the correct OEM connector for the E85 sensor, so no add-a-fuse is needed. Separate harnesses for C6, C7 and C7 Z06.
  • Radar detector harnesses — an ignition-switched, RJ-11 phone-cord connection that ties into the windshield moisture sensor or auto-dimming mirror and hides behind factory trim. C6 and C8.
  • Skip shift harness — plugs inline between the factory connector and the solenoid so second gear stays available on the C7 manual.
  • Rapid fire third brake light harness — flashes the C7 third brake light several times under braking, then holds solid.

Fitment is specific to model year and trim, so check the individual listing before ordering. Several harnesses are built to order.
