    Custom TPI Harness Pics

    I just finished building a 1227727 TPI harness and thought it would be cool to share a few pics. The TPI Harness includes 700R4 wiring. The harness is for a TPI powered full size Chevy Pickup. The computer will be mounted near the passenger side front headlight, which is why there is about 5' 6" of length from the computer to the rear of the TPI manifold. The harness includes a Heated O2 Sensor Connector, Park Switch, SES, and Brake Switch wiring which makes for a nearly painless installation!
