Painless wiring harness

[RhatterNTatter]

First, hope I am in the right area for this thread.

Second, pull bodies off of both 1st series (54 Chev and 54 GMC) as well as off of 59 GMC to do frame stuff, motor stuff, etc.

So, my question is how to order up painless wiring harness for these....can't find a match up to any search criteria....closest thing I found is "GM 10201" and not sure if this is what I need....want to match up to the donor electronics on motor, starter, etc. and to body electronics for the original lights, switches, gages etc.

Any help on this would be greatly appreciated.

Also would like to know how to get to the NC/SC area for locals folks who might want to do some swapping or at least story telling.

Thanks....I am really busy trying to get my dustless blaster delivered and will work on figuring out where to advertise that service in here...
