Re: Electric Trailer Brakes
Inspired by what John had done, I went for a Tekonsha P3 also. I was in two minds as to whether to go for the cubby location or somewhere on the right. Then, on another site I read of someone locating the controller in a most unlikely spot, just under the dash, about mid-way between the two brake pedals. There it is out of the way, it can be seen through the steering wheel by moving you head slightly, otherwise it is nicely obstructed so as not to distract on those long night drives. The manual lever can still be easily activated by reaching down. The downside is that it is vulnerable to being kicked. I would certainly remove it if putting the car in for a service. Luckily it is very easy to remove. If it doesn't work out I'll probably put it in the cubby but so far so good.
My wiring was somewhat different also. The four pig-tails supplied, I took into the centre console. There I earthed the unit to an existing earth post. The other three leads I took more or less diagonally across the body and under the carpet to the trailer harness socket under the rear left quarter panel. On the battery side of the socket I spliced the power lead into the thicker red wire with a 20A line fuse. The fuse is probably not necessary since the red wire is fused back at the fuse box anyway but I felt it would be good to provide a bit more isolation. The stop light signal lead I spliced into the appropriate lead at the socket. The third lead (brake controller actuator) I connected with a spade connector to the blue wire on trailer harness that is terminated loose at the trailer harness plug.
A point to note about Australia's stupid automotive wire standard that measures the outside diameter of the insulation. For the stop light signal wire I used 3mm wire and 4mm for the others. As you might know, the blue electric bake wire in the trailer harness seems quite skinny and certainly skinnier than the 4mm I was using to take it back to the controller. I considered this blue wire to be the weak point. However, when I connected the two, this "skinny" blue wire had considerably more copper in it than my 4mm supposedly top quality Aussie Narva brand wire. So now the weak point is my wiring.
