Intergrated Trailer Brake Controller

[DaHo]

I bought a 07 1500 Seirra with the towing package but it did not include the Intergrated Trailer Brake Controller. I have a regular trailer brake controller but would like the intergrated model so it will work with the trucks brake system and all the info will be in the drivers information center. Can I add it and where can I purchase this?

 

I saw this doing a search but what is a RPO JL1 and how do I know if my truck has this?

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

 

Condition/Concern:

Some customers may request that dealers install the factory Integrated Trailer Brake Controller on their 2007 or 2008 Full Size pickup when the vehicle was ordered without RPO JL1.

 

Recommendation/Instructions:

This is to advise you that if the vehicle does not have RPO JL1, it can not be retro-fitted with a factory trailer brake controller.

 

Bulletin 06-08-45-008 or later advises how to install an aftermarket trailer brake controller on vehicles NOT equipped with RPO JL1.

 

Bulletin 07-08-45-001 or later advises how to install an aftermarket trailer brake controller under certain conditions if the vehicle IS equipped with RPO JL1.

You've answered your own question, you can not retro-fit with factory trailer.
