Expert Reply:
The replacement needed will depend on which trailer connector your car dolly uses, a 4 pole or a 7-way.
For a 4-pole, a standard trailer wiring harness like # HM48240 would work well for you.
If the tow dolly has a 7-way connector on it with electric brakes, I'd go with something like # 277-000141 to provide the trailer connector and junction box. The junction box allows you a safe spot to make your connections that will keep moisture away from the wiring connections. You'd use a length of wire like # 10-1-1 to run your brake circuit from the junction box to the brake magnets and # SWC4332-1 (sold by the foot) 3-conductor wire for the lighting circuits.
I'll link you to a help article about trailer wiring that you'll likely find helpful.
