5kt/tq wiring harnesses?

[Ameer Antar]

Anyone know of any places to get wiring harness other than the dealer? I'm
gonna replace most of the 4ga wires for the batt/starter/alt circuit. But I
think the copper is just getting old, in other places too. I think a lot
these cars need/will need new harnesses after getting to 15-20 yrs. I
wonder if anyone would keep that in stock either. Do those copper wire
cleaners help w/ this? Thanks.
