So, my other thread got moved to the safc area. Where no one will ever see it again.......

Well, after reading the FSM, I am looking at the wiring diagram for the wires going into the ECU..... or is it called EGI?

So, there are like a ton of different pressure sensors, and I don't know exactly which one it is. I see.... EGR, BAC, PRCV, don't know what those are... is it one of those? I am in a rush because I gotta go to work soon. Please help. Thanks.

This might help.

 

Thanks. That is the howto I am using. But he only shows the TPS hookup. I want to hook into the Boost Sensor.... Can't find it though.

I read all the threads in the SAFC area. And none of them tell the colors of the wires going into the ECU. They all say they will check it out and write later. And never do. Please! Thanks!

What about this one?

 

Thanks. I wired it to the brown/red wire. Mine is an S4, the one he was doing was an S5. Thanks for your help though. Hopefully it all works.

 

So this is an 88 n/a and you want it to read boost on the boost gauge on the S-AFC? Is this what you are trying to do or are you trying to use the pressure sensor (MAP sensor) signal to replace the TPS signal?
