Trailer brake controller install. 82215652

[JLMOPARMAN]

Start by using a trim stick an pull away the HVAC controls.

Remove the connectors and set aside.

Remove the screw from the lower controls.

With 2 hands pull towards you.

Remove the connectors from the lower controls and pull it out of the dash.

Remove the 12V outlet from its housing. This is in there tight!!

Remove the 12V housing from the lower panel.

Install the retainer ring to the lower panel.

BEFORE installing the switch, take the gain knob and without snapping it together make sure the switch is oriented to the “1” position at twelve o’clock.

Snap the gain knob into place with the “1” in the twelve o’clock position.

Gently snap the switch into place.

Snap the brake switch into place

Feed the wire through the opening and reassemble the lower panel.

Find the tapped back connector and plug it into the supplied harness.

The next part is hard to explain. There is a harness that must have its Christmas tree retainer pulled out of the dash support, exposing one of the holes for the controller bracket upper stud.

The nuts were a little fiddly to get tight. I used a 1/4” ratchet with a short extension, no big deal with a little patience.

My controller module did come bolted on 180* from what the instructions said. I left it that way and will report back if it gives me any issues.

Attach the two wires, zip tie everything in place. Reinstall the HVAC controls and your all finished up. Took about an hour and a half.

My thinking says the "backwards from the pictures" should not matter. It does not with others. It should learn the position it is in and work from there. Redarc can be mounted in virtually ANY position as long as it's solid. This is solid as the rest of the truck once mounted, no way in XXXX it's going to move, vibrate or shake. Rock solid, you can't even move it by hand.
I'd be surprised if it won't work this way - making for an easy solution to the extremely close quarters with the big wire bundles on some versions of the JT.
They may have realized this after the instructions were printed and moved it around. Maybe...

And if you are the lucky ones, you won't run into this like more than 2 or 3 of us have -
Since this happens even with trailer connected it means you can't manually apply only trailer brakes on some JTs

I didn’t. Pretty straight forward install, working great. Backlight and green/red LEDs working just like the instructions say, when a trailer is connected.

Just curious - as I've not actually pulled my trailer out (it's a bitch to get back without my front receiver now) - I've only connected to test - did it work mounted as shipped and not turned according to the pics in the instructions?
It is actually a BETTER fit as shipped instead of turned like the instructions.
My guess is it will learn and work perfectly as supplied without turning it on the plate to match pictures.

And yes, I struggled to get the fat wiring bundle pulled out enough to get the top nut in place, but it's not that bad once you get them pulled back.
A 1/4" drive small ratchet, socket and short extension make it easier.
Warm weather will I'm sure make it easier.
If doing this in COLD weather - be careful of all of the clips when you remove the center dash parts -
PULL STRAIGHT OUT, not at an angle, don't pull one side far out then the other, work both ends and pull straight out. Nothing will break if you don't get in a big-a$$ hurry.
in fact, the center part is the easiest part - especially since I had the 12v socket out already and only had to remove the Redarc controller knob.
The wiring for the 12v outlet will JUST REACH to the glove box area. I moved mine over there and taped it in place for later.

I also tested it without pulling the trailer out. Lights all came on and brakes energized so I called it a success.

The only real test, since these depend on motion, the proportional part of the controller, will be when on the road at some speed to see how it manages based on controller settings, etc.
Yeah, it would apply the brakes, but these sense motion like any other, and apply brakes harder or softer, depending on DECELERATION of the truck (and controller itself)

One person has actually towed with it - not sure if he flipped it on the plate or not, but towed a boat and it worked fine. It should, regardless of orientation. But so far, only one person has actually TOWED and said it worked correctly when moving.
When stopped it's only appling brakes based on a button push, not using any electronics in the box for proportional mode as in moving.

Great write up JLMOPARMAN…….made my install a snap. The problem I have is I didn’t want to lose the 12 volt port. So I lengthened the wires to the port and relocated the port next to my ebrake. It took more time to do that than to install the brake controller lol.

That's a brilliant solution. Handy, and you can route the wire from anything plugged into it along the bottom edge or between the panels, keeping it tidy and cables out of the way. Some people are just so creative

This is brilliant - any chance you took any additional photos of the steps along the way, that you could share? Thanks

Does anyone know if the Mopar brake controller works with the Eco Diesel? Description only says Gas engine but I don’t see why not? Great instructions btw

Yes it does….. I installed it in my 2021 JTRD……

Awesome, thanks!

I towed my TT today after getting the Mopar brake controller installed trailer weight is 4000# with the controller turned all the way up to 10 it wouldn't lock the trailer tires that shouldn't be how this works right?

It looks like the 12v cable is not used so it should be possible to relocate it right? I’m thinking to move it to the tray on the dash to provide an easy charging spot for devices.

correct, at 10 your breaks should have locked up. Check your connections on the TT as well as the cornnections on the truck.
