I just did this,,, I bought the summit kit, remove the old positve and neg.. ran new positive from the solenoid to the back to the battery thought the firewall with wire loom on it... Ran down to autozone, got 3 more ground wires that where 24 inces long and had just the loops on each end.. went over to the pass side of the block and on the block, about 6 inches from the timing cover is the bolt that holds the starter wire bracket to the block, I took out that bolt cleaned it really good with sandpaper and put 2 of the 24 inch cables ends on it and bolted it back it.. I ran 1 cable to the sway bar bushing bolt that bolts to the frame, and one to the body where the strut tower bump is (cleaing off all the paint first),,
then in the back I ran the big bastard that came in the summit kit from the neg term of the battery to the wheel hop shock bolt that goes into the frame (cleaned first) ..... and the other 24 inch fro the neg term to the floor of where the spare tire goes ( again cleaned paint off first).. Worked like a charm....... tony
