Im doing an LS1 swap in my 89 camaro. I need to know what these connectors are for?? They are under the dash on the pass side. here is a pic. I know that the Fuel injectors wire runs through them, not sure what else does. thanks

 

If you read the connector pin numbers (A, B, C, etcetera) and list the wire colrs in each of the pin locations, it should be very easy to identify them.

 

but that is the thing, I dont know where these wire go to?? there is no diagram for me refer to. is there any IGN wire on this connectors??

 

That looks like C207. The wires that are pink with black stripe are ignition hot. Two of them are injector power. Do a search on C207 and it should yield your answers. While doing your swap you will become very familiar with this one and C100(firewall connector).

 

You don't need to know where they go. The connectors are right there, in your photo. They should be marked with pin designations, such as "A, B,C..." or "1, 2, 3..." so you can tell which wires are in which terminals. That information shoudl be enough to allow decoding of the connector number, and which devices are connected to each wire.

Bingo, I was thinking C207, since the pur/wht was a dead giveaway.

 

Yeah i did a search and found what i was looking for. Just didnt know what the connectors were called. Im in the last stage of the wiring. I already have the 89 camaro C100 all figured out. Should be ready to start up. thanks

 

I can pretty much call out C207 for a 90 from my swap. That is where your ses light hooks in, injectors and ECM get ignition power, speedo, some transmission functions, and VATS. Learn it, love it, live it,Good luck with your swap!
