Ok I'm still trying to diagnose my cruise control issue. I think it has something to do with my E-brake switch.

My other thread is here (http://www.dieselplace.com/forum/showthread.php?p=2882084#post2882084).

I just need to know where my e-brake switch is and how to test it?

Thanks

It should be a button switch located on the e brake assembly. Use a 12v test light to check if it is working.
