    discoll trailer wiring

    Does anyone have a wiring diagram for the discoll trailer plug, or know exactly what all wires go to and from? I was going to use the " wal-mart" converter harness, but others said they had issues with this kit. I as others need no more issues!

    I haven't had any issues at all with the Hopkins converters, which is what walmart sells, or at least used to.
    Wire colors for the plug inside the back are in the ETM.
    Alternatively, just use a test light to identify them.

    Hopkins converter works fine for me. There is one that requires power and one that does not. I have the one that requires power. Other D2's i have seen have the one without power. I would suggest the one without power, it works and one less wire to find and connect. Mine came to me on my '01 D2 from the previous owner so I did not wire mine, but I did move my brake lights to the bumper, upgrade to '03-'04 bumper lights and move my backup lights down and signals up. So, I used RAVE to get the wire colors, but since I like to have a quick answer now and then from others without digging all the time I will share those colors here for you. Find a safe place under the rear of the body that is metal and sand it good so you get a ground and take the white ground wire from the Hopkins kit to that point using a round crimp on lug and a sheet metal screw.

    All you really need I believe is one of the LH & RH turn signals, and tail light wire to match up to the Hopkins 4-wire converter kit. Check the directions, they are pretty clear once you know your vehicle wires.

    Wire colors inside the upper rear tail lights. RAVE Manual, Electronic Diagrams Pg. 49.5 or Pg. 100 of 126 in the PDF pages count
    Red-Yellow - Rear Bumper Fog Lights
    Green-White - RH Turn Signal
    Red-Orange - RH Tail Lights
    Green-Purple - Brake Lights
    Green-Red - LH Turn Signal
    Red-Black - LH Tail Light

    Trailer Socket Colors per RAVE
    Blue - Rear Fog Lights
    Green - RH Turn Signal
    Brown - RH Tail Light
    Red - Brake Light
    Yellow - LH Turn Signal
    Black - LH Tail Light

    You're better off running the ground up inside the rear pillar to the common body ground. Doing it on the body underneath will eventually lead to corrosion and a failed ground.
    I suspect people who have issues with the Hopkins converters didn't hook them up well, they used scotchlock connectors, wire nuts or crappy unsealed crimps.
    If you use high quality uninsulated connectors, put in a dab of dielectric grease and then seal them well with adhesive lined heat shrink, you'll never have any problems.
    You only need the powered converter if you have a whole lot of trailer lights.
