Just got the car and was installing my stereo system. I got 2 out of 3 of the BIG 3 upgrade done. I got the Alternator to the battery and the battery to the chassis. The last of that would be the wire from the engine to the ground/chassis. Where can I find that? I am assuming it is somewhere under the block. I cant really trace from the top of the engine. Any help woild be perfect.
