WOW.....this is by far the best link and layout I've seen in the past two days of searching for what I'm looking for! This is no question a keeper...and I will for sure be using it! HOWEVER! >

I'm going to chalk this to an Operator Error... the layout is so good cuz you just go to the "name" of what U are looking for and presto...awesome info........THE PROBLEM ...

I don't know the NAME of what I'm looking for??? I know it's NOT fuse box, or fuse panel, or fuse wires... It's "CONNECTORS under Fuse block"....no such thing....so to me it's Mystery Connectors!

Please look at this video......go to picture frame 2:20 he's pointing at these two fat connectors. Mine one is in pink tape on the left......the other one on my right is forresent green tape...what are these connectors for? specially the pink wrapped one! on the left?

Again Ron..........GREAT GREAT LINK !! I just don't know the name of the connectors so that I can figure the rest out!

Originally, I thought you were talking about connector(s) attached to the fuse bock on the underside, but you are not. Those are other cables going who knows where. Sorry I couldn't provide your answer.

It's been about 3 years since I last touched any GM electrical and connector diagrams, probably since I graduated high school. But I can guarantee it's all there. But nice to see Ron found a alternative for free. If only that existed in my field. Funny enough I don't really drive my LBZ anymore I lost interest and moved onto Mercedes-Benz diesels but I'll still lurk once in a while. And I'm glad it's been able to help some people.

Thank you for the link. WOW what a lot to learn and sort through. Is there list or table to explain all the acronyms such as TBC BATT fuse? What is TBC? I've figured out BCM as body control module but are they for and there seem to be many. Where to find them? I have issues with no over head interior light, no back up lights. (2007 chev 2500 HD with a diesel engine)

Thanks

It pains me to even say this, but AI apps like Grok and Chatgpt are very helpful tools for questions like this. They do a good job summarizing available information in a way anyone can understand.

Throttle Body Control ??? your issue is a fuse or relay?.......or the wires on the floor on the drivers side got wet? test at the beginning source...then go from there... Also look for a mouse in the house!...due to the rev lights and the interior lights are not related...but both run to the same mouse house! chew chew chew.....those dane critters🐭🐁🖱 ohh and ps always check be sure "grounds" are up to par

Thanks. Don't know anything about AI or looked into it. Google is about my limit.

There were droppings in the "under the hood fuse box". No sign of them having been in the cab. I have fuse box cleaned up. I found blown fuses there and the panel left side dash. Understandable with the mess of wires at the rear. I think every fuse is good now and holding.

When I got this truck a few days ago, almost all the wiring to the rear was severely damaged. Only the turn signals worked. All the wiring including trailer was dangling. It had one bundle going up to the side of the box for 5th wheel connector which was fine, those at the rear where almost unrecognizable. By the appearance of the taping the bundles look original. I now have all the turn/tail/ stop light wiring repaired and working except the BU lights.
