It sounds like your 2000 Olds Bravada did not come with a factory installed 7-Way wiring harness. The Tow Ready Custom Fit Vehicle Wiring, # 118384, is designed to plug in line on a vehicle that has a 7-Way wiring harness already installed on it. It then provides a 4-Way wiring harness.
It could still potentially work but you will need to make sure that the white wires are grounded to the vehicle frame in a spot that is clean and free from corrosion. A better solution would be to use # 37185. You would attach the left turn, right turn, and running light wires on the vehicle to the 4-Way part of this harness, ground the white wire, and tape up the other wires that will not be used.
