90% sure it is, the other choice is the knock sensor if its a turbo, but i think that is with the TPS branch of the harness

Yeah sorry I forgot to clarify. This is an 87 NA FC.

Funny you bring up the knock sensor though...did the 87s have a gray knock sensor wire? In the diagrams, im supposed to look for a gray one...but Im not sure what / where that knock sensor would be...

the NA didn't have a knock sensor. the turbo does, and i think its white? although its shielded and the shield is gray
