how do I wire my trialer harness on my 4500?

[machinemover]

I just bought a 4500 2 days ago, I am setting it up and it dawnwd on me, there's no trailer plug! The brake conroller plug is there under the dash, but what do I need to hook the rest of this up? I need the big round 7=wire plug setup.

On the back of the truck is the bundle of wires for the 7-pin trailer plug.

You will need one of the 7-pin connectors and a mounting bracket for it.

gives you the wire color and its function coming from the truck.

Trailer Wiring Diagram For 4 Way, 5 Way, 6 Way and 7 Way circuits



(scroll to about 1/2 way on the link) gives you the tow vehicle side of the 7-pin connector and what each pin represents. (be mindfull of the notch in the plug and note its location).



Good luck.

Thanks for the help guys, got it done today. A bit of a hassle since nobody use a standard wire color, but I got it done. Thanks
