Hello. I added cruise control to the vehicle that did not come from the factory. This include steering wheel switches and flashing the computer for cruise. Still the cruise control doesn't work. In reading the technical bulletins this should have been all that I needed. In further research it looks like their might be another switch, cruise deactivation control. Typically this connects to the brake master cylinder. My brake master cylinder has no port or switch nor can I even find a wiring harness for connection. I have looked under the dash and there looks like a couple of harness plugs that might be for this switch. There is a brake light switch which also from the parts list is called the inhibitor switch for speed control. I am lost on what is missing or why the speed control doesn't work. Any testing, parts diagram or other would be greatly appreciated.

Thanks,
Do you

Thanks for the reply. The particular part your reference is for the switch that mounts into the brake master cylinder. The master cylinder for my vehicle does not have this port for this part. I had thought that the newer electronic speed controls did not have a servo and did not need this. Also the diagram you attached is does not show this switch. I guess the real question is do I need this part and how would it install in my vehicle?

Thanks.

I am sure you would need the switches, you might just be better off trying to find an aftermarket cruise so you can put that in as it sounds like you have factory unit yo are trying to adapt to your truck. The problem is in different vehicles some of the wiring is not installed so itmakes It hard to try to wire in stuff like that.

I prefer to keep it factory as all the components are there. The two pictures of switches you sent I believe serve the same purpose. In my case I have the brake pedal cut out switch. I am going to test it to verify if it is working. If it is working, then something went wrong with the Dealer when they flashed the memory for cruise. So to sum up I believe the components for this vehicle for factory cruise control are the steering wheel switches, the brake pedal cut out switch, and the computer. Given this equipment and programming of the PCM, the cruise should function. Would you agree?

Thanks.
