I'm trying to upgrad my alternator to a 3g on my 89 McLaren. The McLaren came with a 130amp Lestek Alternator similar to the ones used on the SSP's. That Alternator used the 4gauge wire along with the black/orange wires. Should I use the 3g in the same manner or eliminate the black/orange wire and only use the 4 gauge? The write ups and videos vary so much, I'm confused now.
