Dual Alternator - which wire

[34gtp]

Just finished up putting dual alts in my truck. In the article in the members area it says where to tap into the factory wiring to power up the second alternator but not which wire on the plug. Which wire on the new plug do I use?

Send Roger ( GMC Hauler ) a PM. I'm sure he'll provide the info you're looking for.

Ok I'm curious to know if there is/was a dual alternator setup for the 94 year 6.5 trucks, I'm using the serpentine setup from a 94 in my 82 and I would one day like to run dual alts.
