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?

 

Subject:Adding Integrated Trailer brake Controller RPO JL1 - keywords connector electric hydraulic itbc tow towing wire wiring #PIT4332B - (08/16/2007)

 

 

 

Models:2007-2008 Chevrolet Silverado

 

 

2007-2008 GMC Sierra

 

 

 

This PI was superseded to update model years. Please discard PIT4332A.

 

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.

      The Peckish Synapse

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
