After searching for an hour to no avail and getting utterly confused by the factory wiring schematic in the FSM I traced down and figured out the Dodge wiring colors for the 7 blade trailer connector.

Center= purple/black tracer PL/BK back up lights
1 o'clock= red/orange tracer RD/OR 12v Power
3 o'clock= brown/red tracer BR/RD Right turn and brake
5 o'clock= light blue LB Brake Controller
7 o'clock= Black BK Ground , (mine has two black wires)
9 o'clock= Green/red tracer GR/RD Left turn and brake
11 o'clock= Black/orange tracer BK/OR Running lights

This is looking at the connector from the rear of the vehicle.

Hope this helps save some time.

 

That is sure better then touching random combinations of wires together hoping you don't get a little smoke fire.......

 

HA ha, got one!! That's why I bothered to do this...

Shoulda unhooked the batteries, but figured a fuse wasn't a big deal if I blew one...

 

Kurt,
I just want to make sure I got your legend correct. Is the legend for the male plug on the truck?
The reason I ask is that my brother-in-law has a problem with his travel trailer. Every time he plugs it into a truck (many trucks tried), it blows a fuse in the truck and he gets no running lights on the trailer. I need to find the short for him over the winter and I am assuming that I want to read your legend in reverse if I am trying to figure out what connector in the female trailer plug I should be working with for +12v to the running lights.

 

The "female" connector is the one on the truck, looking at it with the cover open, the running lights are the pin at 11 o'clock.

 

These are the colors commonly used on a tailer, could be different than the tow car.

 

Just wondering if that's an old schematic? Up here 7 wire trailer wire comes...
white, red, blue, green, yellow, brown and black.

Blue = brakes
white = ground
yellow = back up/auxiliary center pin if used.
black = 12v +
red = L stop/turn
brown = R stop/turn
green = lights

 

I don't think it's old. It IS SAE standard trailer wiring colors and positions tho. Maybe Canada is different, I dunno. Never heard there was any difference between the states and Canada but it certainly could be.

 

With all of the brands of pre-wired and molded plug ins/socket that I have bought, the colors varies from mfr to mfr. The standard is not so standard anymore. Use the largest wire gauge for the high power demands.

 

Regardless of wire color, the pin position for function is pretty standard. That diagram is very clear on that. Grab a small UPS battery, some test leads, commission the DW for lookout, and have at it.

Could be a not-so-smart past owner solved the problem of no brake controller by wiring the brakes to the tail lights and putting a no-blow in the tail light circuit.

 

I realize it's possible for someone to use any color wire for any function I just didn't realize that the "standard" is different in Canada from the US, its good to know also being Tallguy is from Alberta he could be working with the "Canadian" colors.

 

J_Martin - that picture is EXACTLY what I need, thanks a million. As for a previous owner playing with the wiring, the only thing that doesn't surprise me on this trailer is what the PO didn't mess up. He sold the trailer as having A/C. It does indeed have AC, he bought a cheap unit that you would in your window, cut a huge hole in side of the trailer and mounted the A/C on top of a cabinet. I applaud his ingenuity BUT the water pours into the trailer every time it rains and the A/C is on the windward side of the trailer I could go on ad-nauseum about the bodged modifications but suffice it to say, any diagnostic work on the trailer is an adventure in trying to figure out how someone could modify something in a way I could never imagine.

BTW - I have always just assumed that the pin in the middle would either be ground or the +12V connection.

 

Nope. There used to be a 6 way connector. Center pin was added for back up lights. Otherwise they're interchangeable.

 

The above diagram is in fact SAE. busboys listing is "Bargmam" who I think invented the piece of kr**. Bargman is used by most of the RV industry.

 

I have a White/Brown tracer leftover in the wiring that lights up when the brake is pressed...any idea? My taillights work fine
