Primus IQ Brake Controller Wiring Functions

Question:

can you get me a wiring diagram for Primus IQ brake controller?

Expert Reply:

The Primus IQ # TK90160 doesn't have instructions that come with a wiring diagram, but we have a picture/diagram on our site that shows which wires are connected to which functions on your vehicle. I attached the diagram for you to view, the wires will be connected as follows:

White - Ground
Black - 12V Power
Blue - To 7-Way at rear of vehicle
Red - Cold side of stop light switch

If you are needing a new pigtail for your Primus IQ it is part # 7894. This same harness will work with most Tekonsha and Draw-Tite brake controllers.
