Used Search and still need help

[Cherub]

I had Nelson Performance Rework my lq4 harness. It may seem daunting but its plug and play. little is used from your exisitng harness, and what is used can be traced down with a chiltons and a flashlight. I used a 91 suburban gauge cluster, for the speedo control. There is a diagram floating around here of the correct connections that need to be repinned.

I also went with a lokar flex cable for the gear selector. The room was tight and it was the easiest solution.

I dont know if you plan on staying with the wire throttle body. but thats something you will need to decide. If you dont then you will have to wire in the TPS and IAC. just tell whoever makes your harness.
