My build is coming along just need the little things now

No one has made a step by step guide to wire the Hemi into the old cars. However you can purchase a wiring harness and stock PCM to control the 6.1L from Hotwire.

As for wiring the entire car I used an American Autowire kit as I found easier to do. If you find my build, I have shown some of my wiring. Some of the parts like the GOLD box and wiring of the alternator is done with the engine harness.

As for LED's you'll have top use the stock sockets as no one remakes them. I do know I was able to use Dodge Neon sockets for the front grill and rear lights on my 76 Duster.
