Where to route wiring harness - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Where is the factory wiring harness from the fuse block routed to the rear of the truck?

Through the firewall to the engine well and then towards the rear of the truck?
Inside the frame?
From the rear of the cab and into the truck box?

The PO was really creative- so far I have removed more than 600 feet of 12/2 house wire with twist-on connectors, both in a large variety of brilliant colors.

I don't care about exactly stock- this is my daily driver- but I would like to follow the factory layouts as much as possible

My new Painless harness from Summit came today and I am like a little kid at Christmas- the truck has been down for three weeks.

Anyone have a picture or two to share?

Thanks!
