I have an early 99 truck with no cruise control from the factory. I have recently installed all the wiring from a late 99 truck that had many options that compliment the ones I've recently installed including electric windows, door locks, overhead console, etc.

The one thing that I'm curious about is if my original hydroboost will cause any issue with the proper function of cruise control. I've heard of Hydroboost with speed control. Is that a must for cruise control to function?

Thanks,
Drake

 

im not sure but i would think you would all so need the pcm for it to work.

 

I do have an newer pcm that I installed for the purposes of using Autoenginuity to display rotational velocity. I am assuming that would take care of it.

Hey Drake. I don't know much about cruise control, but I know I have a sensor on the brake cylinder that is a backup for the sensor on the brake pedal. Look below the brake cylinder bowl for a sensor.
