I'm in need of some wiring help.

My truck in a 2004 and currently has a cheap old Tekonsha Voyager trailer brake controller, at least I think it is. Tekonsha Voyager Trailer Brake Controller - 1 to 4 Axles - Proportional Tekonsha Brake Controller 39510



It's plugged into the factory harness under the dash. It works fine, just looks like crap. I always hated the way it was just screwed to the bottom of the dash.

When I re-did my dash - here: https://www.ford-trucks.com/forums/1...lift-pics.html

I replaced the lower half of the dash with a 2006 panel. It has the upfitter switches and I also got the factory brake controller. I removed the Tekonsha with hopes getting the factory unit to work.



The Tekonsha only has four wires - red, white, blue, and black. The pig-tail wired to it has red, white, blue, green and brown. I assume the green and/or brown are connected to the black wire somewhere under the tape.



The factory 2006 controller has the red white blue and green wires. I'm assuming those will transfer straight over to the plug where the Tekonsha was plugged in. Simple enough right?

BUT......... The factory 2006 controller also has several other wires coming out of a separate plug on the back next to the red white blue green plug.

Does anyone have any idea how to go about wiring this thing up to make it functional? Or am I doomed to use an aftermarket controller? I'd really like to get the factory unit to work and install it in the dash next to the upfitter switches where it goes.

 

That brake controller only works on 05-up f-superduty

 

So there is no way to wire this thing up to make it work? No way at all?

 

No, that controller has to be programmed to the trucks pcm. And on 05-up that did not have a factory tbc, you had to add a kit that also included a new brake master cylinder. 04 model year pcm are not compatible with factory tbc.

 

Well that sucks.

Thanks for the explanation though.

 

I guess my question now for the group is........

How can I test this factory unit to make sure it's not dead and.......

How much is it worth if I wanted to sell it - here, ebay, craigslist?

 

hmmm... did you try it?

you might be able to get it to work, it just won't be as "integrated" as a 2005 or later model.

 

I like your thinking! But no. I didn't even try wiring the normal red,white,blue, green. Maybe I will to see what happens LOL!

 

The engineer in me says there is an emergency mode. Something to keep the braking alive if the PCM communication fails.

You would perpetually be in error, but you would have trailer brakes. They would not be pressure proportional, however. They would likely be timed like most after market controllers are, but you would get the look you want.

 

I tried searching the part number in the pic that is on the brake controller to see what a new one costs, but no luck. Either that's not the actual part number or it has changed over the years.

 

2006 was a strange year.

They usually put them on the driver side of the console. The '05 we had at work was that way, and my 2008 is that way.

I've never seen one on the passenger side.
