I have an '02 F150 XL that I'm installing OEM power windows and locks on. Need the relay #4 inside the cab for the one touch down window function, but since I don't already own the relay, I don't know which one to buy. It's a helluva crapshoot to try to find this at a junkyard, and junkyards also aren't very accommodating to taking my 3 month old daughter with me.

Searched this site and google and can't seem to find any answers.

Thanks
