2025 A quick one about bussing with Aptiv/Delphi and Deutsch style connectors. Aptiv uses a "fir tree" clip, or one that some people refer to as a "rose bud" clip. GM has noted they do not recommend the use of the "fir tree" style clip for reasons I agree with, they tend to be a single use...

2025 back to the interior tear out. We finally got the front seats, center console, and carpet out the front.

Alright, today's theme is going to be complications and changes in plans. Warning LONG, run away now. This has turned into a deep dive of wire so if you already know the basics or dont care to see if you can help fix anything I get wrong just skip this post and go to the next. All of these OE...

The Gep Power products Maxi fuse PDM moves away from the Aptiv system of terminals and instead uses the Lear Mak 8 terminal. The Lear terminals are quite robust and nice. There is one big downside as far as I'm concerned. Lear doesnt give good crimp specifications or have recommended tooling...

I had previously mentioned the issue with the traditional underwood electrical center was the maxi fuses. I looked up multiple alternatives from Bussmann, Gep Power Products, MTA, Dill Blox, etc... I had considered switching to J-Case fuses, Midi fuses etc. After weighing out the pros and cons...

Thank you for the compliment and for taking the time to read through.

2023 I had also mentioned earlier in the thread systems for sounds and thermal insulation. Here we can see what GM used, as an example. While taking the rear (middle for the suburban) seats and breaking down the original installation. Clearly there's the edge rubber, and plastic coverings. Also...

2023 I had brought up earlier that the ceiling panels were held up near the edges in some locations, most notably by the windshield with a type of plastic clip that held velcro and that I could not find the replacement piece, so I had to make a replacement. here is the original piece... I...

This photos are pretty fantastic.

From the technical manual: The Power Distribution schematic shows the wiring from the Battery and Generator to the Starter Solenoid, Fuse Block, Ignition Switch and Light Switch. The first component after a Fusible Link is also shown. In certain instances, the first component after a Fuse Block...

Going into this I was learning GM's specific language in their schematics. It's not a consistent language exactly, the decisions seem to be made by teams of people. I wanted to use GM's language as much as possible so that the manual and schematics of my alterations aren't jarring when going...

I have not, but I do know that the York will handle it easily and others have connected all kinds of air horns to their York. With a tank big enough it wouldn't matter though it might limit the length of time. You really aren't going to go wrong with any of the above recommendations.

For a truck that size, personally, I'd go the same route I did on my truck, a converted York compressor that uses engine power. But the Viair that was suggested is a very respected unit.

2024-25 I pulled the the lighting harness, making sire all the lighting works well...and figured it would be an easier harness to take apart and learn from as well. The harness runs from connector C102, by the firewall to the front of the truck then takes a right turn to the passenger side and...

2024 Cleaning up the starter and making new wires for it. The 4/0 welding wire is actually closer to 3/0. Ended up changing the lugs for a better fit. internal layer of braid mostly cause it was already on the wire. Convoluted loom non-slit, gonna seal this up for this wire, It's EPDM and...

2024 Here is the t-tap that had been installed for the VSC's A/C signal. To address the t-tap on the A/C signal wire, I used a metri-pak bus and used that to house the A/C diode as well D104. In this pic you can see the old diode housing still wired. It's a bit bulkier, but otherwise I am...

2024 Here you can see the inside of the traditional electrical center used by GM in the 90's. After 20 some aught years the insulation has some damage due to vibration and here also you can see the large bus rail for the maxi fuses. Each rail has 4 terminals and there are two for the electrical...

Once I started looking, I just kept finding things I didnt like and needed to address. And to think it all started cause I put some grease in my ball joints. pressure switch for air compressor, floating. Need to move the welder to make room for the second battery. This is how the original...

2023 The Variable Speed Controller for the Flex-A-Lite fans died. Opened it all up and now I'll be addressing all of this wiring, ugh. While im here... Green wire goes to the A/C Compressor for signal override. Under this tape? Another t-tap. traced the ignition signal wire...fuse taps. No...

Roughly same timeframe 2023 Bought a new grill...can you spot the immediate problem? These aftermarket grills are not as robust as the OEM and not as robust as the older aftermarket ones either so Ive heard. If I'm going to go through the bother of plastic welding and fixing this I might as...
