how to incorporate addictional running lights properly?

[jumpsoffrock]

Where in the harness would I incorporate additional running lights on the bed? These lights have been there forever, but the way they were wired in is non-existent and I would like to not only re-do it, but do it the way a professional shop or factory would.

The rear wiring harness in my truck is butchered, and to add insult to injury, the mess that's left behind looks like it has been torn to shreds and is hanging from every corner...

...in other words nothing is hooked up and nothing works.(in the rear of the truck).


Which circuit would I add running lights without overburdening any circuit?
