Need some auto electrical advice!

[Ch2500HD]

Hey guys, just wondering if anyone has enough experience working on auto electrical systems to point me in the right direction.

 

I've got an 03 2500HD with the 6.0L. It is mostly stock; however, here is my plan for it.

 

Mods:

 

1. KC HiLites 130W driving lights (one pair)

2. KC HiLites 55W backup lights (one pair)

3. Recon Accessories 15" Mini-LED taillight bar

4. Whelen Hid-A-Way strobe lights ( two pair) powered by a Whelen 60W power supply

5. Whelen TIR 3 LED grille lights (two pair)

5. Painless Wiring 7 circuit waterproof fuse block

6. Add second battery that is isolated from the main battery. GM code TP2

7. Install switchbox inside cab.

 

My question is how do I wire all of these accessories? If anyone knows of a wiring diagram for my truck please let me know where to get it. I tried the Haynes manual but it said it wasn't for the HD trucks. Or if anyone here knows how to wire this please give your advice. I want to have a single switch panel located in one of the openings on the console. I would like to have only three switches: driving lights, backup lights, strobe+grille lights. Also if anyone knows how to wire up an auxiliary battery that functions the same as the GM code TP2, because the dealership said it was a build & assemble option and had to be done at the factory and couldn't be retrofitted. Sorry for long post

It won't be the easiest thing to explain from a distance, but I'm an electronics geek with a computerized GM Factory Service Manual on computer.

 

Send me a PM and I can start by sending you a bunch of the pages from the manual.
