stock wiring and stand alone operation

[Cheeseman]

Ok gang, probably a very remedial question for many of you, but I am second guessing myself and some info I have been given (away from here). I have my LS1/4l60e installed and sent the harness and computer off for programming and harness thinning. I have everything back and installed. When I was begining to work on my factory underhood wiring harness installation, I wanted to thin out what will not be needed now that the motor is a stand alone unit. The new motor/computer will take care of the alternator, so is there a reason that I need the factory 1967 voltage regulator or its associated wires? I can see where all my headlight/marker lamp wires are routed and needed, but I did not know if I could thin out the 1967 alternator and voltage reg wires? There is the main red 12V 12 or 14 gauge wire that runs through that harness, am I overlooking its needed use in this facet? Does it feed power into the cab for powering up something needed in there? I was told by a source (that I do not have a lot of faith in) that I could just ditch all that stuff....I am thinking that I may need to keep that red 12V wire.....it is the wire that goes to the passenger fender to the junction block.


I have the pigtail to the starter figured out as well and think I am good there.

Any guidance is greatly appreciated.

Thanks!
