I have a 91 teg and I was wondering if anyone out there had the wiring diagram for a turbo timer hook up. I have a apexi tt and I just want the instructions on how to hook it up to my car. I have never done it and I have never turboed a b series car. I know how to do it. Just one poor kid who can't afford and will never pay to have someone else work on my car. Thanks for any help that is given

 

I don't know if it too late. But I've install my Turbo timer on 96 GSR pretty simple. the Apexi TT have the A/F ratio thing too right? if so than you need to slice into the ECU wires. I thinks there's two that going to the ECU 1, Ground 2. O2 sensor. Go to Apexi.com for instruction. They have a map of your ECU and which wire to slice. All the other wire from the TT should be connected to Igniton wire. Take off the ignition cover(the big plastic that cover where you insert you key). Or you can buy a connecter for 10-15 dollar on ebay. One connect to the TT and the other end connect to the Igniton. Pretty simple.
