Much better than a Youtube video that tried to explain it. Their underdash wiring was a bit "blurred" so to speak. The colour coding chart is great.

 

BTW, the Brake Controller Harness shown on page 3 is identical to the harness that came w/ the P3 I bought last year. I just saved it because I was using the P3 w/ the Tekonsha GM "plug & play" harness for my '04 GMT800.

Just wanted to say thanks to compulynx for posting the great instructions. Wired up my Prodigy Primus IQ today.

Putting in my Prodigy P3 tonight. These instructions look to pretty much cover everything. I just have one question. I see where it says to install a 40 amp fuse for the power feed, do I also need to purchase and install a 30 amp fuse to power the other stud? If so, where does it go? Thanks for the help

You only need the 40 amp fuse.

I installed my P3 today in my '11 2500HD. I don't know why, but the red/black circuit 742 wire & 40 amp fuse were already installed from the factory.

 

Everything else was the same as per the instructions posted above

Thanks for providing the write-up. I just installed my Tekonsha P3. I had already found the 6mm & 8mm nuts and I purchased a 40 amp fuse before I got started, but the entire install using your guide took 20 minutes. Very well written and much appreciated by many. Thanks!

The site that had this is now gone. Did anyone happen to have saved the pdf?

 

Edit: Nevermind. Found it on page 2. Don't know how I missed it the first time.

Its a PDF, so you will need acrobat reader. It is big, so it takes a few seconds to load.
