What did you do to your NNBS GMT900 Tahoe/Yukon Today?

you might be able to get them working temporarily using the tp92/95 that I posted earlier I just looked in my fuse box I would imagine either one of those pins would either take 12v or a ground, you would need to check the pin to see if it it's hot or not, then hook up a toggle switch, janky but it would give you wipers (i think)

Does that book have an actual diagram By chance or does it just have pinouts?

I got it working! Its real meth-y the way i’ve got it set up right now though. Pics incoming

So this is real methed up, but heres how I’ve got wipers right now. Its an Add-A-Circuit in the stock wiper fuse location, that goes to a light switch, that then goes to the purple wire on the wiper transmission. When purple is switched high, the wiper controls in the cab work fine. So when i park the car, i will pop the hood and turn off the light switch. This will get me by until this weekend when i can pull a replacement junction box from the wrecking yard and add another body ground

Update: that didnt work. I mean, it did for a while but it blew the 25 amp fuse. I think i need less/ heavier gauge cable.

I bet your wiper motor is going south and drawing more current.

Update: no dice. :/

it just shows the pin out, there are limited notated diagrams in the manual, it's a .pdf that someone made and sold on ebay, there may be more diagrams but this file is like 11,818 pages long, lol
so when I am looking for something I just search using a keyword

***and being the nnbs trucks are more serial bus controlled than the older trucks it's more dependent on the bcm, a single wire can control multiple devices via serial data bus

So I'm looking for replacement junction fuse blocks for the tahoe, I bought one from the wrecking yard that came off a 2008 LT Tahoe- its got a sticker on it that says "SX" whereas the one off mine has a sticker that says "UT" and there are some pins on the bottom that are different. Mine has a few extra ones in some places and the parts yard one has a couple that are missing. I'm reading on GM Parts Direct that the actual part number is compatible with all LS/LT/LTZ trim levels? What gives? I have all the fuses pulled out and the panel is sitting in the oven set to 190* drying out.
