I would assume that withthe factory7 pin, every pin is hooked up, correct? I need the back up light for my boat trailer brake disconnect.

 

lepack...I checked with my dealer and they couldn't find a part number for a harness, so...I ended up creating my own with split-loom and I tie-wrapped it along side the factory harness that follows along the drivers side frame. It's no big deal, I added 2 wires - the blue trailer brake circuit and a 12V hot all the time circuit for trailer interior lights etc. Like I said, I didn't bother with reverse lights, its in the factory harness and I suppoe it would be easy to tap into ... I believe from what read here and there, it's a light green wire.

h3 dude, I would assume that the factory 7-wire would be wired to the standard config. Easy to compare your H3 socket to your trailer wiring with a cheap test light type probe, assuming you know how the trailer is wired.

 

Thanks canukh3, that makes sense.

One more question. I went hunting for the blue brake wire that dead-ends in a connector behind the battery as you suggest. Is this it?

Yes it is...to confirm, there should be a light green wire on top of it at the connector point. From there, I cut the blue flush with the connector and used a good butt splice into my harness. If you didn't want to go that extreme you could fish that wire out and use one of these;
