ECM Ground
On a 1990 TBI 305 camaro RS
Which wire in the wire harness of the ECM is the ground wire?
and where is it generally grounded at?
I'm trying to check if it is grounded properly.

Re: ECM Ground
At the ECM, D1, D6, and A12 are grounds. They go to the engine block, most likely the rear of passenger side head.
Note that D6 is the O2 sensor ground and is isolated in the ECM from the other two grounds.
