Trailer hitch question

[Dan Robertson]

I have just installed a "DrawTite" trailer hitch on my 05 Escape. It fit like a glove with no drilling or welding at all. My question concerns the wiring harness. My vehicle does not have a factory tow package but it does have a pig-tail behind the rear bumper (right side) that appears to be for trailer lights. The owners manual shows a fuse for trailer lights and I found that I have no fuse in that spot. Closer examination revealed that the spot in the fuse box is blank, there is no connectors for a fuse to plug in. Does anyone know if there is a way to energize those wires behind my bumper? I have purchased a wiring kit but I do not really want to tap into the wires behind the tail light lens if I don't have to.

Never used mine but the wiring on my 05 is on the driver side bumper.
Never looked for the fuse box wiring.
Now I am curious.
