Hello, do you have a switch on the knee bolster to the left under steering column?

thanks, ***** ***** do not. You would then need to go with an aftermarket unit brake controller. Actually, they work better than the factory ITBC. You can select one for your model and follow instructions to install. I have included a couple links to look at, If you had the ITBC? you would have the switch as well as control module on the frame,. I will add there was a recall for the module from factory and,, they had problems over the years, Best fix? aftermarket controller

here are the links
