that's what i'm using a mallory ballst resistor also all my grounds are either in 4 guage or 8 gauge.my battery is in the trunk so i'm grounded from the [-] side of the bat. to the r/rear frame then from the neg. side of the battery to the trunk bulkhead and both of those are #4 gauge wire. now the engine compartment i'm using an #8 gauge wire from the firewall to a bell housing bolt. all my grounds from the unilite and power scrubber go to the stock alternator bracket.now from there i'm again running a #4 gauge wire from there to the r/front frame rail.the ground picks up from there and then goes to the core support then finally to a fender bolt were the stock ground wire is located at.
