I have attached a photo you can use to connect the Replacement Power Switch # EJ-3520-PSW to your 3,500 lb RAM jack. We don't have a direct wiring diagram but if you notice even though the wires are the same colors they look pretty different so you can use this to easily tell which wire goes where.

Thank you for the picture! I purchased the Ram 3500 and after installing it, it didn’t work! After testing the battery, replacing the fuse, I finally took the top cover off to find out none of the wires were connected! It’s raining now so I have to wait to connect everything tomorrow. Fingers crossed ??
