I don't have a wiring diagram, but I'd be happy to explain it for you.

In order for the reverse solenoid on a Hydraulic Brake Coupler like # DM62VR to function, one of the two wires leading from it needs to be connected to the wire from the center pin of the trailer connector, which is typically the yellow or purple wire (use a circuit tester like # PTW2993 to confirm). The remaining wire is grounded to the trailer frame.

On the vehicle side, you'll need to make sure that the center pin of the 7-way is connected to the reverse lamp circuit.

I've linked to our trailer wiring help article, which you'll find helpful.

All you should need on the fifth circuit of your 5-way is a 12 volt signal to activate the reverse lock out. Have you used a circuit tester like part #PTW2993 to verify you have 12 volts on that pin? Looking at the condition of your 5-way it is also…

Answer 9

If the solenoid is getting a full 12 volts and is grounding properly it should be shutting all the way. Since you said it is clicking that makes it sound like it's getting power. You could try improving the ground circuit but most likely…

You very well could use wheel studs instead of bolts by installing screw-in studs like the 1/2" x 2" Redline #25-53 or #25-51, or the 9/16" x 3" Redline #25-11. Just be sure that the stud is the correct size, the middle opening on…
