Vannin' Home Forums Ford How to... backup alarm install

1990. E150
I have a backup alarm with a black ground wire and a red hot wire.What color wire will I be looking for on the van? Is there a way to hook it up with out drilling a hole from inside the van? Can it be wired to my trailer wires?

You are talking about a beep beep beep alarm for when in reverse , right ?
If so, the Red hot wire will connect to the hot wire for the back up lights. Sorry I am not sure what color. As for mounting, when I had my shop, we just bolted them to the frame as close to the rear of the van/truck as we could.
