Hey all. I installed a new hitch onto my Ford Transit 250 2021 and wired up everything seemingly correct, and the lights didn't turn on. I checked with a multimeter and there wasn't any power so I'm confused on how to check whether my cable is bust or if It's just not sending any power. Appreciate if I could get any help here.

 

With the cable off the vehicle , is there power at any of the plug pins at the back of your vehicle`when parking lights are on? There should be.

Where did they connect the rear plug wires to ? Any parking light wires?
