    What year is it? If it's a factory tow package, there SHOULD be a plug in wiring harness for it. Might make it a little easier or atleast be able to find a schematic on the wire colors.

    I'm also looking at junk yards to see if they have anything. I called dodge and they said I have to but the hole dam thing. Its 115 for the hole thing.

    Above is what I found for the 4 pin connector. It should help get you close. The easiest is probably to get out the test light to verify.

    In the 7 pin connector you will have the following wires I am unsure of the colors dodge uses...
    Ground
    Electric Brake
    Tail/ Running Lights
    Constant + from battery
    Left turn/ Stop
    Right turn/ Stop
    Aux- Activated with reverse

    You just need the plug? the harness connector is still good? You can buy the plug separately from Dodge find a better Dodge parts guy.:nod: we should have OEM on the shelf.

    If you get the adapter you can use any US car connector. The adapter is a Valley product.

    See we got jumpy and cut it all of. :dizzy: But we did keep the 4 pin and 7 pin seperate.

    This is why I'm shopping junk yards to see if I can find a factory 7 and 4 pin and a few feet of wire.

    The only wire on the 7 pin we know for sure is blue which is the break controler.

    The ******* jams I get my self into. :cry:

    A test light, pencil and pc of paper... Can you just check each function on the truck( lights, R turn, Lturn, etc) by turning that function on and checking and marking what wire is "live" ?

    Well we got the wires figured out but there dim as hell on the trailer. Odds are bad ground.

    Sound slike a bad ground or a loose connection for sure. Are all the lights dim (both turn signals and running lights) or is it just one fuction that is dim?

    Both are dim and half of the time we never got the running lights on the trailer to work. I'm at a loss.

    Take a test light with a ground clip on it, and start poking wires. Ground the test light really well and see if the light is bright or dim. If it is bright you have a bad ground on your trailer plug.

    We used a volt meter and most of the wires we tested where right around 12v.

    What is "around 12 volt?" 12.13 or 11.96. you need to see what kind of voltage is available..
