Wiring Electronic brake controller in a VZ Adventra

[smokeybear]

I am about to install a Tekonsha P3 Electronic Brake Controller for towing our camper trailer. Although other threads have said the Adventra doesn't have wiring to the dash for an EBC, when I started to look at how I would run a cable down to the 7pin plug at the back to connect the trailer brakes to the EBC. I undid the 7pin plug and noticed it already has a blue wire connected for the trailer brakes.

Does anyone know where this wire terminates, I tried to follow it but was very hard to see where it goes or if it just terminates in one of the connectors behind the rear bumper?

the blue wire would just be cut and taped up behind the drivers side tail light.

Thanks axemurderer, after digging around a bit, in the end I just ran my wiring right through so the brake controller is it's own system.

Most trailer plugs have the blue wire already wired into the plug and it will just finish wherever the rest are connected.

I have this exact controller for our camper trailer and I wired up two cars to take it. I have a plug on it, so I can just unplug it from one car and plug it into the other.

I figured that might be the case, I borrowed a cable tracker to find the blue wire but it gave really undefined beeps, I think it may have been confused by lots of stuff being earthed to the body.

In the end it wasn't too hard running my own cables, I just need to hook the trailer up and do the brake setup before our next trip.
