still trying to figure out the actibrake wiring diagram... specifically, the note about providing +12v to the center pin of the 7-way 'auxiliary hot wire'

does this mean my voltmeter should be reading a +13~14v charge across the center and ground?

... I've got a thing or two to say about the dealer I bought from...

Hi, this is interesting because the center pin on my tow vehicle is for "Back-up Lights" in-which, my trailer doesn't have, nor do I have disc brakes. So this pin is useless on my set up. So let me get this straight, Actibrake wants you to rewire the back-up light circuit on your tow vehicle and connect the, un-used, center pin on your trailer to what?

Bob,

I think what they're saying is, use the center post for anything in the trailer that requires auxilary power, and not to use the charge line/Actibrake 12V. line for providing auxilary power. If you had back up lights, you would continue to use the center tap.

It might be because the center tap is typically wired with #14 wire, which isn't sufficient for the Actibrake. The charge line is normally #10 wire.

It's not a clear and concisely worded diagram.

finalcutjoe TAKE YOUR UNIT AND TRUCK TO THE AIRSTREAM FACTORY AND GET IT WIRED PROPERLY. sorry

I just went out side to look at my truck 7 pin plug, I can point out 3 posts so far that contradict each other, and the 4th post will be MINE.

all 7 pins on my truck are being used there isn't a positive 12 terminal for charging your trailer, contrary to GMC 30 amp fuse that is supplied for a 30 amp trailer feed?????? the backup pin wiring is being used on the truck and the trailer.

If you start custom wiring this trailer plug you could have problems when towing another trailer.

As before, this post is more negative than it should be but I hope its helpful.

my truck is a 2002 duramax

Relative to your actibrake, I hope I get this right;

1) Your actibrake goes to sleep (no power draw) if it does not see a blue wire pulse for some period of time. Not sure what that period of time is, but I think it is around 2 hours or so.

2) The motor/pump gets power from two possible sources; Black wire when not in break away, Brown wire when in break away.

3) Depending up pressure, you can get a very large inrush current into the motor, and at full pressure I think those things can consume say 20 amps or so from black wire.

4) Relative to your current draw, when you hit the brakes you sent a blue wire pulse and thus "woke up" the CPU and such, and thus the actibrake will draw its motor off current for about 2 hours.

I think this is about right.
