Because I was having fan issues and I had the reinforcement beam rebar w/tow (BT4Z19D520A) and the parking aid wiring harness w/tow (BT4Z15K868D) I thought it would be a good time to install the factory tow package.
First, I ordered and installed the tow package radiator (BT4Z8005A - autozone replacement) and updated fan (RF-259) and towing module (BT4Z8B658B) assembly (local ford dealer),
Next I installed the parking aid wiring harness and the reinforcement beam rebar trimmed the lower valance as outlined in the reinforcement beam rebar instructions and got it all buttoned up.
I confirmed the parking aid sensors were working and proceeded to test the 4-wire flat trailer plug with a plug tester and a meter and the plug appears to be dead.
I checked ground continuity and it's good, no the stop/left/right signal wires have no power when lights are on and turn signals and 4-way flashers are activated so I'm not sure where to look now, any help would be greatly appreciated.
