Hi, I'm looking to re-wire my truck from scratch because the stock wiring has been chopped and added to so much I figure it would be good start over afresh. Has anyone attempted this? It's a diesel 6.2

I guess apart from not requiring gas ignition wiring who makes the easiest to use interior wiring harness?

The HEI wire on a gas harness can be used to activate the diesel injector pump. It probably needs to be a bit longer and there may be a few other minor changes that I can't think of right away.

Interior will be the biggest task. I recently found all the terminals that were used in the fuse block online, they are made by Delphi, and it helps to have the correct crimper to make them nice.

Or are you planning on gutting it and buying a new fuse block and everything?
