Video Transcript for RAM Electric Trailer Jack with Footplate Replacement Power Switch Review

What's up everybody. It's AJ with etrailer.com. Today, we're gonna be checking out this replacement power switch for your RAM Electric Jack. It's gonna be a replacement switch for your jack. So if the button breaks over time, or even the bevel cracks and just doesn't look good and you wanna replace it so looks like new, you can do that. I like that.

So you don't have to buy a whole new jack. It's not too bad to replace. There's a little bit of wiring. Let's get right to it. First thing we're gonna do is remove the screws on the outside.

So there'll be one up here. One on the back side, and one underneath. We'll back all those out, set 'em aside. Underneath here, we'll back out those screws. You got the silver ones up front, and then the gold ones towards the back.

With those removed, I can separate the two portions here. Let's go and remove the bottom one. Set it aside. Now this portion, we're gonna have to pop out the switches. You just push on the backside of them and they pop out.

The wires are gonna be attached underneath. So I suggest checking that out, taking a picture of both sides and make sure you wire back up. Cause there's gonna be six wires that have to go back in place. Then it's gonna get a little crowded in there. There is six different connections, but make sure you run the wires through this portion. And then connect the switch, cause you don't wanna get it all connected and realize you have to take it apart to pop it back in. Another tip would be, transfer one wire at a time when you're going from the old switch to the new switch. It'd be even more helpful just to do that. That way, you know they're going in the right spot. With the wires run, before I pop the switch back in, let's make sure it works. Looks like the jack is going to retract. And also extend. So now I can push this rocker switch back in. Overall, I like that there's a replacement for the switch. The fact I don't have to buy a whole new jack is very helpful. Now it does take a little bit to wire, but it's not too bad. I've done it a couple times. And as long as you take pictures or pay attention, or even go wire by wire, it won't take you that long. Now you can't get a whole new assembly as well. So if this is scratched up or damaged, you wanna replace this too while you're already rewiring it and popping those the switches, you can pick that up on our site as well. Well then that does it. Thanks for hanging out. Hope this helped..

The switch was promptly shipped.This part wasn't a close fit, it was an exact replacement! And my installation is an improvement over the original. As originally equipped, when you pressed the down button, the jack went down and the trailer went up. Makes sense, but it's been driving me crazy for years. I flipped it over. Press down arrow, trailer nose lowers. Makes sense to me.

Good, reliable switch. I also bought a head cover for the jack to keep it that way.

by:
Wouldn’t fit the 3500 ram Jack. It is jack specific. Not just a 3500 Jack. Was sending back but talking with Matt told me not to. Was not cost effective. Thanks
by:
Down worked but the up didn’t. Ordered this guy as a replacement and after a quick wire diagram search the up and down worked as it should. No more ratchet and relaxed forearms.
by:
The product did not fit as advertised, but being an electrician I was able to adjust it to work properly.
by:
Was the wrong switch. Could not find a replacement switch. I don't think it's available. Had to buy a new jack.
by:
Was a perfect fit for my Kohree electric jack. So glad I didn't have to purchase a new jack as it was just a worn out switch.
by:
The switch will not fit correctly and need additional wiring to replace a RAM 3550 switch, sad.
by:
Returned, not the same size as the one in which it was replacing. Needed EJ-3550-PSW, had to get from the jack manufacture.
by:
My Ram electric tongue jack quit going down with the down arrow depressed. The jack would raise with the up arrow depressed fine. I ordered a replacement switch from Etrailer, it arrived very quickly. I watched a YouTube on replacing the switch. I replaced the switch, process was very easy. One thing to note is the wire connectors have a release that has to be depressed when removing them from the switch lugs. My jack now works perfect!

Yes! So glad to hear that, Joseph. :) I appreciate your note, too!

edI recently purchased the Ram Electric Trailer jack from you guys. I test it after install and everything worked. A day later the jack would up down but not down. I performed the grounding procedure you have online and still not working. So, I bought a switch from you and boom,,, it worked. Would you consider refunding what I paid for the switch?

Sincerely,

Jon R

I know that this switch is specific to model number EJ-3520-BBX. What is the model number of your jack? I am happy to see if we have the switch on our site.

by:
Perfect match to what I wanted to replace.
by:
Very good customer service I emailed about my delivery and received a call back with in 10 minutes.
by:
Works good.
by:
Got it within a few days and installed it in 5 mins and is working fine
by:
The part I received was not the same as in my lift jack. My failing switch is a 4 pin and the part I received was a 6 pin. I'm guessing the 6 pin is the most common replacement. In the future I will disassemble before ordering.

Sorry to hear this isn't the right switch for you. We have two switches that look like they have similar pins as yours does, two different sizes. Part # 37213635 is 1-47/64" tall x 61/64" wide and we have part # LC49MD 1-13/16" tall x 1-1/16" wide. You would want to double check your size to make sure it will fit in properly. Let me know if you need anything else, Paul!

@PaulW Glad we could get that corrected and we apologize for the inconvenience. We appreciate you choosing etrailer!
by:
An exact fit very easy install
by:
My RV Front Jack switch failed for no apparent reason. This was a good replacement. Be careful replacing these switches as they come in varying sizes and wiring configuration(4 wire vs 6 wire). Only etrailer had the size and wiring I needed.
