nice write-up! worked perfectly!!!

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. :fume:

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.

    • This is interesting. My quote tagged here is different from my original quote. After I’m driving them longer. That isn’t me. I don’t talk that way. I definitely wouldn’t express myself that way. Interesting.
    • I have the same running boards on my truck and I do agree they are bulky. I also find myself stepping over them when getting in and out of the truck. Besides providing protection to the rocker panels, they aren't very useful.  I will be replacing them soon with the Amp Powersteps. 
    • Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

    • Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.
