hmm i only saw 2 coming out of the engine part of the harness and on near the ecm. i guess ill have to snoop around for some more. also besides grounds, the 12 volt constant and switched wires and the fuel pump is there anything else on the harness that needs hooked up
Engine to frame, engine to battery, battery to frame, harness to engine, harness to battery. These computers are very "ground" needy.
there are 2 grounds on the rear of the engine and 1 ground close to front drivers side coming out of harness.
I'm assuming your not getting any codes.

There are actually two that bolt to the driver's side of the block down low. One comes from the engine harness, the other is the battery ground.Originally Posted by 468Blazer
