Much appreciated sir, thank you.
One other question. When routing the harness, where is the best place to route it from inside cab to the rear for tail lights? Thanks again,

But thank you.
Brad - where did you go from inside cab to outside?

I guess I'm not doing a good job of explaining what I'm asking. How did you route your wiring harness from inside the cab to the back of the truck? Is there a hole somewhere that allowed you to get them down the frame tail from inside to out? Thanks again,
Jonny

Nothing else is required as the harness branches all come through that large hole in the firewall with the exception of the leads to the starter you see going off to the PS (2-wires, red/blue). https://www.flickr.com/photos/advance-design_parts_co/8129206782/in/set-72157631867396207 | | | | | Joined: Dec 2014 Posts: 69 Wrench Fetcher | | Wrench Fetcher Joined: Dec 2014 Posts: 69 | Brad - thanks again for taking the time to answer my questions. Hopefully I'll get some time soon to start installing the new harness.
