Just want to know what other MY2014's are doing.
I think I might have issues with the dealer so I just trying to get my facts straight first.
I have rang another dealer and they told me they splice into the wiring on a MY2014.
Please Any info would be great.
Cheers Brad.
Brad,
I think the reason you are not getting a response is because most people have MY11-MY13's and there are not many MY14's with towing setup as yet. Hang in there, and you will get a response. However, I can tell you that if 1 brake light comes on, then all SHOULD come on. There should not be a situation where only some light up.

There is definitely a problem with your install, as I mentioned earlier. I wouldn't be waiting for a response from here- I would be getting it resolved ASAP with the dealer, as it has not been done corectly.

All brake lights should illuminate with the pedal or manual lever on the brake controller. No exceptions

Xdra10, will check for you tomorrow. I am currently working night shifts and will be off tomorrow so will check lights in the afternoon for you. I'm running P3 in MY 14 limited.

First off I am testing with a North American model Jeep but I will tell you this.

The wiring for the Prodigy DOES NOT activate trailer lights, they are controlled by the vehicle. The brake trigger causes the Prodigy to be active but it doesn't output brake lights to the trailer.

If you use a P3 or P2 manual actuator bar it DOES NOT activate any brake lights. Now I know you guys don't get the plug but you wire in the the P3 specs so I don't see how the controller could engage lights. I verified this on a 2011 Durango and a 2014 Jeep with the factory plug and factory converter for the brake controller. All brake lights on pedal. None on manual actuator.

Edit: to clarify, I can see how with the different trailer setup that the trailer lights on yours would come on but I don't understand the vehicle brake lights thing (what I am curious about here).

Might be a difference with the export models, I have a P3 connected into a 2011 grand cherokee Laredo CRD connected via the trailer harness behind the L/H rear trim panel, all brake lights come on when applying the brake pedal, all brake lights (trailer and all GC) come on when using the manual lever

But how on earth is it triggering the brake lights? That part is the thing that doesn't make sense unless something is back fed. Here is the wiring diagram for the P3... It only has 4 wires and none of them are supposed to go to the brake lights, just the actual brakes on the trailer. I was under the understanding that the P3 shipped globally the same, are you guys saying there is a different PIN out for Australia?

Edit: possibly to do with the different Trailer plug of course? But as you can see there is no output for brake lights from the controller, so how does the manual leaver send that signal anywhere?

Here are my thoughts on the issue...

One of the wires on the brake controller connects to a "brake sense", e.g. on many cars, the simplest way is to connect it to the brake pedal. The P3 is designed to back feed via this line. i.e. when you manually activate the lever, it pretends to be a brake switch going into the pressed state i.e. it puts 12v on this wire. I can confirm 100% that on my Subaru Outback, wired up this way, will light all 5 brake lights on the car&trailer. It will also disengage the cruise control.

As I understand it, though have not checked yet because I only picked up my GC on Saturday, this is not the [best] way to wire a GC. Who knows what the 4-pin connector that you US guys have does, it could connect to a dedicated pin on some ECU that none of the Australian auto-elecs/dealers know about. I can't see how you can draw any parallels between US and Aus.

In Australia, as I understand, the brake controller brake sense line is being connected to the rear of the vehicle. There are possibly 4 places to take this signal from:
1) LHS brake light
2) RHS brake light
3) Centre brake light
4) The connector for the trailer wiring

Without a schematic of the car wiring or tracing it back, how do we know the relationship between these signals. On old, more simpler cars, these were all one and the same signal(wire), in fact they were also directly connected to the switch on the brake signal itself.... And the Cruise control module... And the ABS system.

Likely, all 4 signals that I listed above will "work"(i.e. activate the P3 when you press the pedal) but IF they are different signals coming from an ECU, may not work the same for the P3 back-feeding the manual override. It's possible(and I'm speculating until I can play with my jeep) that if the signal is taken from (4) that the ECU also "listens's" to the signal wire in case a brake controller tries to back-feed the manual override. To me this is the safe thing to do. If I'm applying brakes, the guy behind be should know about it!!!

Ok, we are mixing 2 topics, now I need to clarify, you are telling me that when you hit the override bar on your brake controller that it turned off the cruise in your car?

If this is the case you have a completely different P3 in Australia, as there is no output from the Brake Switch input on the P3. I am not talking about Cars specifically at this point, just that the manufacturer (Tekonsha) wiring diagram as provided in my prior post does not have "output" on that line. Having wired this system the old way, I know there is no voltage coming from the P3 on that wire.

Anyway, I am just as interested in being educated on this subject because I understand there are a lot of things that are different there. I have never seen a brake controller that can interact with a Car in this way other than ODB2, so I am interested to know if your controllers are different.

Mainly, this is because you have an Aussie with an apparently working brake controller but no lights with the bar override, which works as designed as far as I know...?

Are you talking about Xdra10? Read back, as I understand his LHS and trailer brakes ARE coming on for manual override. His RHS and centre are NOT coming on.

I'd be interested to know, those in Au with GC+P3, does manual override disengage cruise?

Yes, and I can see how the trailer brakes may come on the way it is set up just not the Jeep, but we will see.

I should also test what happens when both brake pedal and the override lever are applied but the missus has gone to the gym.

Yes it is curious how the CAN senses that the override lever has been applied. I think coreys has the answer.
Very interesting, Looking forward to seeing if Cruise gets interrupted
