I am just having a little trouble figuring out where exactly to run these wires. I understand 2 of the 3. One wire goes from the negative battery terminal to a metal surface on car (sand the paint away). Then another goes from the Positive battery terminal to the alternator top connector...with fuse... and the third is the one im not getting. From the engine block to the chasis...Hmmm... Im not too engine literate. Where is this? On the bottom of the engine im guessing? I looked and dont see any wires down there other than ones that look like they go to sensors. Thanks GUYS!
