I need pinouts and connection colors for the wiring harness on a 87 tpi. I'm changing a car originally equipped with a four barrel to tpi. I'm now in the process of removing all the four barell wiring in order to swap to the tpi harness. I need some info on this. Thanks in advance for all your help.

 

Come on guys. I know someone out there has some info.

 

I'm going to start installing my new harness this weekend. I need some info

 

If you were a little more specific in WHAT you need, you might get more help.
I assume you're looking for the c100 and c207 pinouts?
You will get great results if you hit the magical button ...

Well I got the harness installed this weekend. Found everything the old fashion way, trace it back. Only thing is I got a conector with 3 wires on it. two pink/white one brown. I was reading somewhere about these wires and it said it supposed to be a pink for injectors, pink/white for injectors, and brown for fuel pump. Where do these go. There is no connector under my dash for these three wires. Would I be able to just run these three wires to an ignition on hot wire?

 

What year TPI did you swap in?

I'd be very hesitant to connect anything to the pink/white wires because the standar key-on wire color is pink/black. But some older years might differ (that's why I was asking about the year of your TPI setup).

A picture of the connector and its location would definitely help with identification.

It's possible it was pink/black. I can't get a picture of the connector, but it came off a 86 305. the connector is comming out of the computer harness, through the side wall. it's right there with the ecm plugs and the dash harness plugs.

 

What ECM pin does the brown wire go to? If it's let's say A2 on C1, it's for the air select valve. If it comes from A10 on C1, it might be for the vehicle speed sensor buffer.

I wish I could point you to an online schematic but our ATGO (Austin TGO chapter) website is down for host change so the schematics are offline. You can go to the Autozone website for schematics.

Correction.. Sorry. The brown wire is for the cooling fan. I looked on chevy thunder. They say the brown goes to the fuse box to hook with the existing A/C-heater fuse. Got that. The other two are for the injectors. It is pink and black. ChevyThunder says to fuse this to an aftermarket fuse block. So would these two go in with the ignition switch?
