Trailer brake controller on 09 Denali?

[stevek]

I know there was an option for the integrated trailer brake controller on the Denali, but I don't have it. For $200 what parts does it actually come with? Part numbers?

At least I don't think I have it...

Don't know if this helps....

My 2010 came with it. This is what you get.

Never used it but according to the dealer salesman you can crank up/down the amount of applied trailer brake pressure when you step on the brakes, and/or you can squeeze the two top knobs together and apply the trailer brake.

If I recall correctly, I think the DIC shows you something about how much pressure is being applied.

Yep don't have that... gotta go find the parts now

edit: Is it even possible?

From what I've been able to find out it cannot be retrofitted to vehicles that didn't come with that option (we've had customers ask) since there are a lot of parts besides the actual controller unit. You'd be better off (and it would be much cheaper) to get a good aftermarket unit and integrate it into the dash.

I mean I read on gm-trucks that if you don't have JL1 you can't get it, but I don't think anyone has said anything about it being on a Denali (already having the HD towing package, aux tranny cooler, etc). Maybe my best bet is to just go to the dealer. It seems stupid that a $200 option on a Denali is such a hassle.

It's not the towing pkg/coolers that are different, there is a lot more

This is from a gm-trucks thread about adding it:

Forget it....The master cylinder,brake booster,chassis wiring,dash trim panel,BCM programming is all different,Not to mention the truck must be equipped with Stabilitrak,You also have to add other parts such as a brake controller module and relay.

Sucks because I'd like to add it to mine too but I'll just go for a $100 tekonsha prodigy like I had in my 2500HD, it worked very well.

Well I know I saw that thread, and it says that stuff must be equipped, but with the HD towing package, it has all of those things. I'll just go to the dealership sometime this week and ask about it.

The Denali's all have the HD towing package standard. If you go to build a Yukon on the gmc website, for regular Yukons, you need to add the HD towing package in order to get the integrated controller. For Denali's, all you can add is the integrated controller for $200. I know it would be more than $200 to change all my stuff, but I don't want some ugly thing hanging around by my knees. Plus with the integration, it displays info on the DIC about the trailer brakes and warnings about trailer shorts, losing the trailer connection, etc.

Stevek what year Denali do you have? I've got a 2008 Yukon XL Denali, I'm curious if it is a possible factory option for mine as well. Please post what you hear back from the dealer. I'll also inquire next time with mine (won't be for a couple months unless there are any problems lol).

2009. I think 09 was the first year they offered the integrated controller, might be 2008 though. I'm going to head over to the dealership probably Saturday. It's a busy week with a lot of work to do, but I'll definitely head over there then... hopefully.
