Purchased one of these and am about to install it.A question for those who have them-
Looking at the wiring diagram, they are wired straight to the battery and always on.I dont want to have to disconect/connect it each time I use the trailer and was wondering about fitting a isolator switch under the bonnet near the battery for it.I carnt think of it being a problem.Any ideas....

I had the same question with mine, I spoke to the auto elect and he assured me that its only powering the LED when the vehicle is turned off. So i believe it can stay on for days without draining the battery.

Connect it as recommended by the manufacturer !!
As you say: "Looking at the wiring diagram, they are wired straight to the battery and always on" my Kelsey electric brakes work this way too, creating no battery problems.
Remember you have full control of the trailer brakes even with the engine off this way.

Nick,
I only bought my P3 last week and pondered the same question. At the top of page 3 in the the instruction manual, it states, "Blank Screen" - "Power to P3 but display is in power saving mode (no motion or activity for at least 15 minutes)"
Power to the display is only restored when you touch the brake pedal.
Although a direct connection to the battery, in the power saving mode, I would have thought all would be well? Does this help?
Dave

The two little LED's that stay on go out as you say after about 5 mins and it stays like that till you start the car again.
have had one for 2 years and havent had a flat battery yet.
