JK factory door lock brain location?

Does anyone know where the factory door lock/unlock brain is on my 2014 Jeep JKU?

Also: Does anyone have any wiring info on the brain?

I see you have had 200+ hits but no answer. Unfortunately, I don't know either on our Jeeps. I do know that on a Dodge Ram, same FCA makes that too, that the receiver unit is a small 2" square/rectangle plastic box attached on the back of the instrument cluster panel (backside of the RPM/speed panel). So, if a gun were to my head, I'd guess there? Anyway, this will at least bump your post.

I don't know the answer either, but am intrigued by the question. Do you want to disconnect it?

I'm not sure what you mean by "brain", but the actuator is the mechanism that's triggered by the input to the Wireless Control Module.

I think he wants to know where the wireless control module is.

It's attached to the steering column, under the cover, next to the ignition switch.

I am looking for the receiver for the door locks.

When I push the lock button on my OEM key fob, what receives the signal & where is it located exactly?

So I noticed the red flashing light on my dashboard today. Yea... I am a little slow on obvious stuff at times.

I assume that is a factory alarm? Now I just need to find the alarm brain or maybe I can tap into the wires going into the flashing light?

I am looking for a + or - source when the doors are locked via the remote control. I am going to use this source to feed a relay and power a radar sensor.

Other than maybe pulling a signal off that flashing light, I'm not sure you'll find what you are looking for. The power locks work as a pulse.. momentary voltage to lock or unlock based on the polarity of the signal.

The attached diagram shows the circuit diagrams... maybe you can pull a signal off one of the door wires to do what you want.

Thanks! That is very helpful. Do you have anymore diagrams like that? One for the factory alarm maybe?

I put a line level convertor and amp in my JKU today and while I had the dash out I took a look at the gauge cluster wiring. There isn't much to it and I have figured out some but not all of the wiring.

I tried the website above but couldn't find more info.

Does anyone have a wiring diagram for a 2014 Jeep JKU gauge cluster?
