Re: 72 GMC wiring harnesses help
If your going to use a stand alone your truck harness you have now will be what you use it has nothing to do with the LS swap.
The stand alone should come with a hot 12 volt to tie into the switch and a ground the rest is in the stand alone yours in the truck want be changed at all.

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!
LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
