Has anyone plugged in a brake controller in their 2003 4runners.
The new hitch comes pre-wired with a harness(in glove compartment) ready to be plugged in under the driver's side and able to recieve a brake controller. The problem is most brake controllers have 4 wires and the toyota wiring harness has 5. Which of the five wires is not used. Anyone help?????
