Easy install. Just plugs in and you're good to go. Originally I was going to do the resistor trick with wiring to an up fitter, but I really liked the idea of having an adjustable idle speed, plug and play functionality, and a high quality part. BD delivered on all of it. I routed the cable behind the console under the dash, which required the use of a wire coat hanger to fish it through. Then I mounted the knob on the mounting plate that comes with the kit using a single screw for the ODB2 port mount. Works perfectly here. In the winter, I just leave it set to the RPM I want, and then use the parking brake to activate it as needed. Works great in our Winnipeg winters. Dirty Diesel Customs also got me the part super fast and their site was easy to use. If you're thinking of a high idle switch, you can stop looking and just buy this one right here, right now, from Dirty Diesel Customs!

Works great, easy install.

The boys at Dirty will set ya up
