Hardwired Lockers with OEM Knob

[MikeKey]

Totally possible, it's not a complicated task. You supply them with 12v and they engage. Talking a switch, and relay minimum. I'm just not one for making stuff for other people.

[MikeKey]

I started this project today. I might be willing to make a harness.... Maybe, it'd def be later in June after PWIM and some other stuff.

But very straightforward. Documenting the whole process on my Instagram story right now if you are interested: https://www.instagram.com/boldadventure/

I'll do a separate write-up and youtube video when I get more time. I'm in crunch time before we leave for Moab. And instagram is a very fast method for me to share info.

I am interested, thanks for sharing the link for us!

[olyelr]

So I went to that instagram thing and I can not figure out how to navigate it very well. Didnt find anything about the locker setup. Did see a lot of cool pics though!

And congrats on losing all that weight so far. Thats frickin impressive! You must feel so much better!

[MikeKey]

You have to have the app, to view stories. Sorry. That's just how it works. I realized half way through my posting this content would make a better youtube video. I decided to even use a wireloom, which ate up WAAY to much of my day, lol.

I'm not using the OEM Knob, however. So I'll have to add my details to a separate thread. I'm on a time crunch with Moab, so I also did not buy aftermarket connectors. I'm spliced right into the harness and using a set of 12V relays, 15 amp fuses, and some new switches.

Ah I see. I will have to try and figure out how to get the app.

So with splicing in to the original harness, will you still be able to utilize the original knob as intended for the lockers (not that it really matters, just curious). And did you put any safety switch for them, so they wont lock until the safety switch is flipped?

Sounds about how I did it with my jk rubicon. New switches and tapped into the oem wires. But the factory switches still worked if I wanted to use them... although I never did.

So I went on my wifes phone with her instagram and watched that locker video.

You definitely need to post that here somehow. Lots of good info.

Off topic, but what is that large metal bracket in the rear that has Thuren written on it (I could see it in the video)? Is that to keep brake lines and such in check with the added travel?

I can see running the hardwire harness all the way to the rear axle if you were going to use an OEM connector, but if you’re going to cut the factory wires, might as well do it up at the firewall/engine bay where it would be better protected from the elements and save 10’+ of wire and loom frustration.

I had a hard time tracing, and when I did, I found multiples of that color wire on my 2015. This was also the case at the sway bar controller.

Volt meter.

You could have used two diodes and kept the factory wires connected too. You didn't need to cut the negative wires either.

You could have texted/call me, lol. I would have told you which wire was the locker source and return at the smart bar....

[PWJouster]

relay power and ground the locker wires At the smartbar? thats sounds simple enough... does the smart bar disconnect have the same function as the lockers, in the way that 12V power disconnects the bar no matter what conditions exist?

[MikeKey]

shit works, that's all that matters.

That's a really great question. Which wire is the 12v power side of the smart bar for the coupler?

[olyelr]

Yep, thats just it. There is always different avenues to get something done, and sometimes it may be easier or harder, righter or wronger . Regardless, you tackled this project and got them working

I totally agree! Mike gets full credit and a man-card merit badge for being the first new gen guy with the stones to do this mod on his rig and document it!

After looking at the wire connector diagram for the SmartBar, I see what he means about duplicate wire colors. Why would Dodge/Ram do that when they have a full spectrum of colors to choose from?

I’m not 100% sure but I think all the sway bar disconnect circuitry is internal in the SmartBar. Maybe PitSlave could chime in on this without divulging too many of his secrets.

I was banging my head over that "Light Gray and Yellow and Yellow and White color choice. Ok, maybe when brand new, but I spent 5 mins cleaning and getting out my light and being sure my eyes weren't deceiving me. Worst color combo ever! Yellow and orange weren't bad.

I used the EVO JK/Rubicon manual disconnect on my sway bar. If that is what someone is confused about.

I think they are wondering is if one could simply overide and operate the original sway bar setup with a separate switch, like you just did with the lockers.

It's possible based on how the mechanism works, but I dunno if you would be able to wire directly into the harness itself. That doesn't seem likely.

However..... take a look here. I just took this photo of the smart bar control module opened up. The sway bar disconnect acts like some sort of plunger. Then you have a red and white wire leading to it, along with two smaller black wires. I'm assuming that's a bit like the lockers, based on the diagrams in this thread. 12v power, 12v ground, and sensor. You would have to crack it open though I think to bypass it.

[olyelr]

Yes you might be on to something there. The 3rd wire might be for a sensor, to notify the computer what location its in.

[DamageWagon]

You could hardwire the smart bar but I’m almost sure it would be internal splicing, so you’d pull the housing like in Mike’s pic, drill a new hole into the housing and splice the hardwire wires through the new hole to those wires inside.

The third wire is the sensor wire, correct. The mechanism is a solenoid and acts like a start motor solenoid, but uses a sensor line instead of a control line.

[Retired BLM Rig]

Here's what another member said about the sway bar disconnect on another thread, however he was talking about a 3rd gen. He says that it's a motor not a solenoid, which makes sense because when I operate my sway bar it sounds more like a motor spinning than a solenoid clicking.

That wouldnt work, the swaybar motor only turns one way, pushing the shift fork into disengaged position against a spring. Theres a plunger besides it that registers depth and when its happy it sends power to a an electro magnetic brake that is fitted at the end of the motor and i would assume simultaniously (sp?) shuts off power to the motor. Then all you need to Do is cut power to that brake to release it and let the spring push back the whole assembly back to engaged.(not sure if that will make sense to anybody its the best i can describe it in writing. Its a clever but overly complicated design imo no wonder it never work that long) I was thinking about a way to use a a 3 pos starter style switch that you hold for a pre determined amount of time then when you release it from "start" to "on" would actuate that brake but I came to the conclusion that a cable system would be the simper way to go about it. My swaybar has been on a shelf for a few months now in the meantime and i havent missed it yet...

[Reloaderguy]

Can you jumper the logic board to bypass the speed sensor?

[Retired BLM Rig]

I'll leave this here in case someone else in the future wants to hardwire their lockers from the SmartBar connector.
