I need to install a 03 tahoe alt. In a ls1 swap using a 04 Gto harness. Near as I can tell the Gto harness doesn't have a pcm wire going to the alt. The charging harness is separate. It has a brown and white wire to a odd shaped plug ( Gto only) my Tahoe alt has the standard 4 pin plug witch I believe only needs one wire hooked up. The question is what wire goes where? And do I need the resistor like some of the other swaps? I tried the search and can't find much about the Gto harness to regular truck alt. Swap any help would be appreciated
Thanks

If you have the flat 4 pin connector, all you need need is ignition thru a resistor (65 to 300 ohm) then pin B on the connector. Steve
