Installing controller on '02 2WD without HD Towing. From what I understand all Expys have the factory installed wiring for the controller and this would simplify the job a lot if someone could help me locate them. I found a large loom near the OBDII Port that has red, black, white, blue and strangely yellow wires. Are these the right ones? They go toward the climate controls from the firewall. Pics would be great if someone has them.
