The two wires are meant to be connected to the 120 volt source. The box or the papers with the transformer should tell you which two of the three wires provides the 12 volt output. If not connect the two wires to the 120V source - Be CAREFUL! - 120V is dangerous. Then try, one at a time, touching each of the three combinations of wires (1&2, 1&3, 2&3) to the contacts on a 12 V incandescent lamp (very bottom and threaded side) the 12V pair will give you the brightest light. The other two are 6v.

I can't address the 7 blade connector without more information. I suggest that you go to a place that sells trailer parts.

Not knowing anything about your trailer I don't know if a 2 amp (2000 ma) transformer will supply enough current to do the job.

Expert Reply:
When wiring a trailer connector, it is best to wire by function, as wire colors can vary. We have an excellent wiring diagram on our website, I will provide you a link so you can look at it.

If you are looking at the inside of the trailer connector where the wires mount to the terminals starting at the notch at the top and working clockwise:

1:00 is Black and 12 volt power
3:00 is Green and Right Turn and Brake
5:00 is Blue and Brake Controller
7:00 is White and Ground
9:00 is Yellow and Left Turn and Brake
11:00 is Brown and Tail and Running Lights
Center is Purple and is Optional Reverse

I recommend using a circuit tester like part # 40376 to verify your connections.

Suburban towing package fuse box location


2005 Suburban Z71 4WD I had similar situation. No 12 volt positive to 7 trailer. Under my hood at the fuse panel, the red 12v + wire was connected to Stud # 1 which is on the left side of fuse box. There is a square fuse right next to this stud. I put a 40 amp fuse in it. I use this power to charge a battery in a trailer as I am hauling.

No power to stop and tail lights on near side of trailer


Has this ever worked ? My brand new truck had a bad harness.
I checked it with a volt meter at the connector on the truck.
I wanted to make sure the trailer was ok and that the problem
was the truck connector.
If you put 12 volts straight to trailer do the lights come on ?
If so then check the truck connector.
Then look for loose connection at the connector.
What year and model truck ?
Is the trailer wiring factory or added by someone ?

Trailer Wiring Diagrams 4 Way Systems

4 way flat molded connectors allow basic hookup for three lighting functions; right turn signal / stop light (green), left turn signal / stop light (yellow), taillight / license / side marker (brown) and a ground (white).

5 Way Systems

Same as 4 way system listed above but adds a extra blue wire for brake signal or auxiliary power. Used on pop up camper trailers or utility / boat trailers.

6 Way System, Rectangle Plug 3/4 inch by 1 inch 6 way rectangle connectors right turn signal (green), left turn signal (yellow), taillight (brown), ground (white). The red and blue wire can be used for brake control or auxiliary. Use on a small motorcycle trailer, snowmobile trailer or utility trailer. Can also be used as custom wiring on trailers with 3 light/wire systems. See "Tow Vehicle Taillight Wiring" below.

I want to run a 12 volt power line to a 7 blade RV trailer plug. Where do I wire it into the trucks system so it will go off when the ignition is turned off and how heavy wire and what amp. fuse do I use?...


you should have a unused circuit in the fuse box, or an accesory not being used, depending what you are powering in the trailer i would suggest a 20 amp, but you can go to 30 amp (not recommended)

How do I get 12 volts at the factory installed trailer connector


You are correct. There is a fuse in the underhood fuse/relay compartment that powers up the pin. It is one of the larger fuses and should be labeled as "AUX". Also check that the power wire is connected to the AUX bolt terminal. They shipped from the factory disconnected and the cable was zip-tied to something below the fuse box.

No running lights on camper trailer


Hey Paul, it's most likely a wiring problem. There is one wire designated for just the running lights. What type of plug does the truck have? Probably 6 or 7 way (6 or 7 wire). You can check the plug-in at the truck with a multi-meter to see if there's power at that point. If there is, then the problem is somewhere from the trailer plug to the lights on the trailer. If you have a 7 way plug, the center plug is for aux. power (back up lights on what you pull, if equipped). One wire is power to the camper battery for a breakaway switch, one for left turn and stop, one for right turn and stop, a ground wire, one for running lights, and one for trailer brakes. To determine what wire does what, 1st with meter check volts of all wires w/ truck and trailer hooked up, truck running, power wire to battery for breakaway should show voltage if equipped w/ a trickle charge, brake wire will show low voltage, approx. 2 volts, apply brakes and should go up to approx. 12 volts, put on L turn signal, meter should go up and down, as power to blinker pulses on and off, do the same to determine which is the R turn signal (put foot on truck brakes will show voltage to brake lights AND brakes, continue w/ process of elimination to determine which is running lights, and exactly where power is not going.
