I bought a 1989 Iroc with factory 350 TPI
The kid who I bought it from cut the under dash harness plugs(two plugs) that plug into the ECM.......I went to splice back the wires but noticed that there are three dark brown wires that are exactly the same........one goes to one plug and two to the other......

My question is what is the best and easiest solution to figuring out what wire goes where ?

 

According to the Info I have, pin A2 is Brn, and goes to the AIR PORT switch . Pin A10 comes from the Speed Sensor (TSS). I don't show a third Brn wire, although IIRC, there is a Brn wire that runs through the IP connector for the Fuel Pump.

 

Thanks for the reply darbysan but.........

Ive done more research and I was incorrect.............the c207 connector wires(under dash wire harness to engine harness were cut) .
So if anyone has a complete 1989 Iroc TPI under dash harness wiring diagram that shows where the wires go from the C207 connector to where they go under the dash would be awesome......

Im trying to find out where the three little dark brown wires go to under the dash so I can reconnect them using and ohm meter i guess unless someone else has any better ideas to reconnect these......

All of my wires going to the c207 connector were cut on the under dash harness side about 4 inches before the c207 connector.......

 

you might find some info on this site?

thanks i looked at Austinthirdgen website before................ but the site does not have the under dash wiring diagrams coming from the c207 connector

I need to know where the three dark brown wires go to under the dash coming from the c207 connector so i can splice them back together.........they were cut on the under dash harness side of the c207 connector
