It should be under your dash by your left knee. just put a wire or clamp in the two little hole on

your "check engine" should flash... 1 2a few times then the next is your code,, 33 or 34 or whatever.. try that.
you just might have to unplug your battery wire and re plug it in also,, sometimes these trucks just have to be reset..

ALDL is what is called, put your wire in A/B
