OK I know you're getting tired of all my questions but I am making progress . . . there is a black single wire plug in under the dash . .as you're facing up from under the dash it is just to the left of the steering column . . mIne is connected to nothing and when I ground it . . it sounds like it's clicking something under the hood!! I"m lost on this one . . I figured since it was black it needed to be grounded but I dont know this time!!
