doesn't do anything if there is no trailer connected as far I remember I had a similar one in my 03
What did you do to your NNBS GMT900 Tahoe/Yukon Today?

I do believe the controller needs to see the trailer brake circuit in order to be activated.
That makes sense. So in order to test it other than on a bench, I’d need a trailer that has electric brakes, correct?
if you know the pinout or (look it up) on the trailer connector you could probably get away with connecting a incandescent bulb the way like he does in the video, that simulates a load and should make it operate for testing, or just swing by a rental place that looks not busy and ask if you could plug in a trailer to test your controller.
if you look in the engine compartment at the front of the fuse box there is 2 post's there and each one should have a red wire attached, 1 is to power the controller and the other is to power a trailer.
The wires are there. Not a clean job lol. Also I noticed when I was checking under the hood before I bought the truck there’s a single battery but it’s in the secondary battery location, and no battery in the normal one. I don’t see any battery cables in the normal place to install a second one. Ever see this? It looks like this was set up for heavy duty towing.

Your battery is in the normal spot, other spot behind headlight is the aux position.

ya that's all normal on the gmt900's they swapped things around, maybe the silverado was already modified when you bought it? figured you would already be familiar
looks like you need a fuse box cover or did you pop it off?
what's the history of this thing? looks like it spent some time in the rust belt that power steering pump and line is looking nasty and some frame rust?
check your brake lines
someone hit it in the parking lot? literally just happened to my other car. I was sitting in it at the time. older lady got out and was like oh I'm sorry. I guess I should look when I'm backing up. she didn't care at all. I was kinda taken back. she's like I was looking over there not backwards. joked it has a back up cam and she didn't look at it. even said her kids get in accidents about once a year.
annoying. I haven't had to deal with insurance crap in atleast 20 years. I guess some people just get used to being horrible drivers.
I'm pretty set on getting one of the wolf box 900 pro to try out. Just need to find the time to install it haha. hate to buy it and it sets around for months

I think more people have dementia than we realize. Laugh off everything, never at fault, only think of themselves constantly..
Hopefully they'll be gone sooner than later.. And hopefully I won't get it.. lose a few brain cells here and there, who knows what's left..
all the chemicals in the environment, the food, the drinking water certainly does not help.
the only saving grace is our bodies shed most of it naturally. I think some gets stuck in the brain matter though lol
the amount of free case you have basically decide how much you care about taking responsibility for things these days.

I did not realize GM did that. It looks weird but makes sense as there’s more room to work on that side of the engine. As for the Silverado and its battery…the body shop couldn’t find it and had to resort to following the cable from the starter to where it is, behind the front bumper. The engine bay in that truck is completely modified in order to make room for the wheels to completely tuck into the tubs when it’s aired out and laying on its rockers. The fuse box is relocated to where the battery was among other things. I told him he could have called but I guess he wanted to play the game of “ where’s the battery?”. It’s a fun truck to work on for me at least. I know every square inch and where every module is since I’ve had them all out at one time or another when I converted the interior from an LS to an LT.

I made mine into a parallel 2 battery, all it takes is a battery holder (the same one used since forever), the cable from the battery to the starter (it clips right into the existing harness under the engine) and a ground wire.

After 700+ miles, the readiness monitor tests finally all passed. I blame the cold weather for jacking up the test parameters for so long.
That is a mod I would like to do, especially being as I live where it gets to below zero at times.
Is there a write up with part numbers and whatnot?
the easy to use oem power cable is getting kind of scarce but there are a couple around p/n: 25825642
it is a plug-n-play cable from 2nd battery tray then feeds under the engine to the starter, it clips right on the existing wire harness.
then you need a standard battery hold down

at first I just grounded it to the alternator bracket but later decided it was best to join both grounds together as it should be done anyway as a best practice.
rvc charging with dual battery's-looking for information
curious on how the rvc system is setup with the ppv's with dual battery's does the ground from the 2nd battery run over to the passenger side and thru the sensor?? if so any pictures? or a ground wire part number? thanks for any information

***CAUTION*** I do my own stunts!
There are two different options. One option doesn't use an isolator and one does.
I prefer the isolated option because if one battery dies you can jump start yourself off the other. When connected in parallel without an isolator both batteries discharge at the same time.
I believe there are some write ups in the PPV section.

I chose to do it parallel, simply because the chances of getting 2 dead batteries at the exact same time is pretty much nill, yes you could probably drain both "somehow" but what are the chances? i also did it because I run a good sized audio amp and subs so the extra juice is a win/win
adding a isolator though is also pretty easy to do, there are crap tons of them in the boating marine market on amazon, some with remote fobs and the whole shebang
