Since all you have is the wiring from your old 7-way you are going to want a 7-way with a wiring harness like part # HM47210. You will need to wire it by function to your vehicle's wiring.

I don't know the color codes for your trailer connector so you will need to use a circuit test like part # PTW2993 to determine the function of each wire, label them, and then wire to the # HM47210 by function.

The colors of the # HM47210 are:

White is ground
Blue is brake output
Green is right stop/turn
Yellow is left stop/turn
Purple is reverse light circuit
Brown is running lights
Red 12 volt accessory

I attached a couple videos for this harness for you to check out as well.
