I installed an aftermarket Class II Hidden Hitch on my 2009 Ford Edge. I am towing a 2000 Yamaha Waverunner. My question is has anyone merely "tapped" into current wires in the rear with wire splicers to hook up the 4 prong plug for a boat trailer? I think the $50 price tag on the T-connector wiring harness is a bit much. I paid $10 bucks for the 4 prong at Wal Mart. I know in the olden days my father tapped into the wires already available. I just need brakes, turn signals, and ground, right?
