Good whole truck wiring harness for LS swap?

[bigmoe]

My 65 will get a whole rewire. I'll probably get a universal kit, perhaps an EZ Wire. Is there a particular circuit number I should get considering this will be an LS swap?

I've got american auto wire for mine....very nice kit...i contacted them and told them what all I had on the truck and they recommended the 15 circuit system for what I had...
Make a list of all the electrical components you have and go from there..
but it doesn't matter which truck side harness you use...the LS harness is standalone...I'm using PSI for my LS side ....
To make the LS harness work all you need is constant hot,switch on hot, and grounds...

American Autowire 500560 for mine. Still in the process but the only thing I don't like so far is the headlight harness, you have to make it from your old one, no wire lengths provided just a roll of wire.

used a complete 15 circuit kit then got with PSI Conversions and used their standalone kit for the LS. Worked great.

American autowire for the truck and psi for the stand alone engine harness. I used the clssic update in my 72 nova and was very happy
