    Default 04 2500hd hitch wiring

    Greetings,
    I recently bought an 04 2500HD.
    It did NOT have a hitch.
    I understand the electric brake controllers will attach to a factory adapter which goes into fuse box.
    BUT, what about installing a plug on my new hitch?
    I noticed a covered plug up under the bed by the spare tire.
    Is there another connector that plugs into this and then goes to whatever plug I use on the hitch?
    I did not get an adapter in my glove box.-so am I correct, I will need 2 connectors from a dealer, one to controller, and one from plug in wiring harness up under bed to hitch plug?
    Thanks ahead of time, Mark

    You're looking to install a brake controller on your 04? I think there is a post on this, do a search and you should be able to find it.
