Update. I was ready to dig for wiring today. I have a wire “sniffer” I use at work. I planned to hook it up to the brake controller connection. The brake controller has a dedicated wire that leads all the way back to the hitch because it’s proportional.
Popped off the under dash cover, easiest I’ve ever pulled off because it’s on with magnets. Meet as a pin under there. Well insulated too.
I could not find the connector. I know exactly what to look for because I installed a brake controller in my X.
If the brake controller isn’t there it’s doubtful there is any other wiring in the car. I just watched Model Y brake controller Video and the connector was wedged way down behind the side panel next to the dead pedal. So it’s possible it’s still in there. Model X was very obvious and very easy to get to.
It’s not 100% sure there is no wiring in the back either even if there is no brake controller. Since it’s rated for 3500 lbs often that doesn’t need brakes. But on Jeeps any trailer over 2000 lbs required brakes.
If anyone has better luck poking around please share.
Oh backup plan status:
This is working.
I just ordered a 2nd one. Be curious if one remote runs both or they stay independent.
For braking and running lights it works really good.
For signals there is several issues.
No feedback, no timeout and remote range. So it’s easy to be left blinking and not know it.
I lied there is some feedback. You can hear it, it’s pretty loud. I can hear it at stop lights but not while driving.
Another issue. It barely has the range needed. If remote is on my lap it may or may not reach. If I have it near driver window it works 99%.
I might move it closer and higher on the trailer. That way I can visually confirm in mirrors and range will work. But it’s comforting having the running lights and brake lights at the rear of the trailer. So I’m not sure what to do.
Priority is probably.
Running lights (at night)
Brake lights
Blinkers.
I have high sides on my utility trailer. They don’t really need to be as high as they are. If I cut them down blinkers on Car can be clearly seen. Trailer has no brakes. Probably 2000-2500 gross weight. Can’t read labels and more
I mostly use the Trailer to dump grass and leaves at local recycle center and Home Depot runs.
I have a second heavier duty trailer, gross weight is 5000lbs with hydraulic dumping. Love this trailer. It has electric brakes. I will probably trade it for a 3500 lb version that also dumps and is lighter duty. It has its own battery. For the hydraulic pump.
