I installed a new aftermarket, factory style engine wiring harness on my '72 Cutlass today.

I do not know where the following plug goes. The wiring on this car was a mess when I bought it, so the original plug like this one was not plugged into anything. And I could not find it in the service manual either.

The wires leading to it are green with white stripe and black.

Any help would be appreciated.

im no expert but i think it goes to your tcs...right behind your oil fill tube..the thing with the 3 ports

 

That's where it goes!
