Adding Trailer Brake Controller

[kxlexus]

I have a 2007 GMC Sierra, newest body style, that I bought new. This truck didn't come with the integrated trailer brake controller from the factory or even a trailer hitch. I added a trailer hitch and seven pin connector. Now I want to add an aftermarket Trailer Brake Controller. I have no idea what all is involved and would greatly appreciate some guidance.

 

Thank You,

Steve

Im sorta in the same boat. I'll be adding a controller before next spring. But from what Ive read here, Prodigy 2 or 3 seem to get the most votes. I think on the pre 09 models, you can buy a pig tail that simply plugs in under the dash and you're good to go. 09+ they did away with that plug, and left the wires loose. Just gotta wire them up. Lots of videos online how to wire them though.

I'm pretty sure the under dash connector went away with the 900s. There is a wire bundle you splice into on the 900s.

you're probably more right then I am. I just pulled some years out of my head and took a guess

OP Steve... Looks like you double posted your questiong. Rich answered it on the other post. Looks like for some gmt900 there is an underdash bundle. Here it is:

I put one on my 08 last year. Pretty straight forward. My truck was a tow package equipped truck with a hitch and connector mounted in the bumper and the harness wires were coiled and stowed under the dash left side.

Spurshot is right on just did my 2011 it was same place just follow instructions from which ever controller you purchase it will say which color wire to attach theres to,

It is just 5 wires loomed up there. The great thing is there is a tag with the discription of the wires. i only used 4 out of the 5 wires since my controler does not have dimming capabilities

Spur is correct I did my 2007 NBS back in 2008 and it was pretty straight forward... :0)

When installing the controller, don't forget to hook up the two wires to the posts on the fuse box under the hood. You will also need to buy a 40amp fuse for the brake controller to work. It will show you i nthe directions where to install the fuse.
