Hey all
I have a 87 trans am carb car. I need the harness that hooks up to the drivers side firewall. i could also use the throttle cable(has to be out of a carb car..i believe they are shorter than tpi cables.)

the engine harness ?

i have a cable too

Well..im not running a computer in it...i got rid of it. Im going old school with a edelbrock carb and intake. no emmissions. i just need the harness that goes into the firewall on drivers side.

There are 2 harnesses on the drivers side ( head light harness and engine harness) that connect together & make one piece that screws to the firewall. The headlight harness is the smaller one and the engine harness is the larger one. The ECM harness is the one that leads behind the passenger side fender.

Since your car is an 87 be sure that you buy a harness that has the electrical speedo sending unit wires...........I'm pretty sure those 2 wires lead into the harness your looking for !
