all i know was the ground wire from the intake manifold that ran stright to the passenger side fender got hot and burned the plastic off the wire
im thinking that i hooked up a ground to the wrong thing there is a box cover over some of the harness thats under the intake manifold and there is one wire coming out of it and i think i have it bolted to the block... i think thats a ground wire and that spot isnt a good ground so im gonna try and bolt it to the support that bolts to the intake manifold and the block |
