I need the wiring diagram for the electrical part switches on the EJ-3520-WBX, or if you can send me pictures of the complete wires inside of the EJ-3520-CVRWm to include both switches, thanks for your help.

If you take a look at the diagram I've provided for the Replacement Power Switch for RAM Electric Trailer Jack with Footplate # EJ-3520-PSW which goes to the Electric Jack w/ Footplate # EJ-3520-WBX, you'll be able to see how both of the switches get wired.

Thanks, Bryce for the clear and concise details on the wiring who wouldn’t have been able to put it back together without your diagram. Good job thank you.

My current switch looks like a EJ-3550-PSW with 4 blades and 2 jumper wires. Your web site and expert comments say that the EJ -3520-PSW is the replacement. It has 6 blades. How would I account for the 2 jumper wires
