Draw-Tite 118840 21-C Mustang Mach-E T-One W/Upgraded Circuit Protected Modulite

I installed this on a Mustang Mach-e. It is an in line plug design which is superior (in my view) to the cut and splice one size fits all kit. Getting the series connectors up to the tail lights does take some patience. I wired the kit to the rear power outlet (which shuts off when the car is powered down) because I didn't want to try to run the power wire up the traction battery under the car. The 12 volt is the purple wire on the outlet. I subbed a 7.5 amp fuse so I wouldn't overload the vehicle wiring which limits me to LED light trailers. I scraped off the paint to make ground but put grease on the white crimp joint to inhibit rust.
