Replaces the light board for your etrailer electric jack (EJ-3520-BBX or EJ-3520-WBX).


Worked as designed. Finally I can my camping journey without worrying if our jack switch will work correctly.


As ordered and as description


The light board was for my RAM 3500 series electric jack. Though the board itself was physically smaller in size it fit the slot in my RAM jack, and the wiring also fit just fine. The smaller red wire, that went to the switch was a bit short but I was able to get it plugged in to the switch connector. The light seems to work fine.


Just what I needed


Good product and exact match.


eTrailer service was great as usual.

instructions even though connections were obvious. However for the ground screw I would have to support the trailer and take the Jack apart to get to it. Chose to simply cut the ground wire at the board on the old board. That left me with a wire fastened to the trailer jack as a ground. Cut off the ground screw connector from the wire that came with the new board. Then cut off the insulation and soldered the two wires together. Electrical tape and then liquid electrical tape will prevent oxidation of the connection.

The light works as expected. My original light board was flakey. I leave it on in the evening so folks don't run into the trailer or car hitch.


Fit perfect.


It all fit perfect! I drew an electrical diagram and numbered the wires before I removed the switches from the damage housing. I fed the wires through the new housing before I hooked up the switches. After I wired the switches I seated the switches in the new housing tested it and closed it all up. I thought the cover was expensive but it does save you approximately half the cost of a new jack! I guess one nice thing would be if it came with a wiring diagram .


Easy to order. Customer service very helpful. Got delivery in just a few days and will use again.


works good the only bad thing is that it took 7 days to get from USPS first class mail


Light board arrived quickly put it on the camper works great




Perfect fit. Great service and follow up.
