Looks like that's what I'll have to do, checked the center pin on the socket with truck in reverse and key on and had no power.
I'll have to figure out how to get a connection to the center pin, is there a blade to slide a connector on to?

Some trucks have a wire hooked to the center pin but is unhooked somewhere in the harness and must be attached to the backup light circuit. I don't use a backup light on my trailers so never needed to wire this. Generally the center pin has no wire connected The center pins on plugs I've seen have either a hollow brass tube with a brass screw that you can insert a stripped copper wire into then tighten the screw or a brass screw and flat brass strip to put a wired crimp connector under and tighten down. Just have to run a wire either from the transmission backup switch or truck backup lights down to the plug. If yours is prewired you might check the under hood fuse box to see if there is a trailer backup circuit fuse listed that may need to be installed.
