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.

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

@Brian If your current switch has 4 pins then, you'd want to use the Replacement Light Switch for Electric Trailer Jack with Footplate # EJ-3520-LSW which has 4 pins.

@BryceD isn't a light switch just an off and on? The current up/down switch doesn't lock in place like a light switch. So that would cause me concern

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.
