    • Hello there!  So I am working on installing these door sills using these instructions (because of course, on GM's own site, the instruction file failed to open) into my truck, and I am stuck on step 23, which is where you're connecting the power source to the BCM connector.  Namely, the connector itself appears to have cavity #1 already occupied.  The reference photos also don't really line up either - in the photo below step 25, I see a box with openings for 7 connectors, but the closest box only has 5 - the one BEHIND it has 7...so am I pulling the wrong connector entirely?   Have this all torn apart right now, and could really use a hand quickly!
    • Unloaded Pin weight is 2081 lbs. I'd guess loaded to be between 2600-2700 lbs so at lets say 3400 lbs payload he would still have 700-800lbs.
    • I’m trying my best to educate myself on torque, horsepower, transmissions and gas verse diesel. I’m going to be shopping for a new 1500 as I do not tow anything nor have plans too.    My employer is fortunate enough to have a spare company vehicle that’s a GMC 1500 with the 6.2 10 speed and that thing just cruises up Donner Summit in Northern California going to Nevada. It never downshifts it seems to have plenty of power to climb the hill.    My question to the group - how much of climb is because of engine or the 10 speed being able to find the right gear, or is it both? If it’s the transmission being able to keep the truck is the right gear, would selecting the 5.3 allow me to not notice the difference? Or even better would the 3.0 diesel do better with turbos not being impacted by altitude and more torque down low?    I do other vacations and trips in the mountains as well which would be loaded down with my wife and three kids. And a pick up bed and most likely camper shell filled with crappola.    And yes, I’m typing this post in the garage on Mother’s Day otherwise I’d be in trouble for being on my phone. 😂
    • Battery connections tight?  How are your grounds, clean or corroded?  Any broken ground straps?  Underhood fuse boxes are quite common on this 99-07 and 07-13 trucks so that's a place to check out as well.  Corroded or burnt terminals on the underside of the box, corroded or burnt wires in the connectors to the box.
