Howdy, Working away here and need some help. 70 c10 with a 2002 LS. I have a harness for the ls and a universal American auto wire harness for the rest of there truck. My question relates to the alternator hook up: How do I hook this up? As you can see the LS harness has the plug with the grey wire that runs to the ECU, whereas the American auto wire has the red and brown setup. The American auto wire calls for the alternator wire to go to a plug (4A)that is in the ignition bundle. Not sure if I leave the 4A alone. Will the LS wiring take care of this? Does the ignition switch have to hooked up it? Does the ecu cover this?
Advice and thoughts on this? I might have to call the two companies later, built thought I’d pick some brains here as well.
Thanks all.
