It is actually very easy to instal.after you get the gauges on just and screwd back on the dash figure out where it is you want to mount the switch ( I chose to drill a hole next to the power mirror nob and put the switches there). Then get the Black wire and mount it to somthing metal like under the stering wheel Panel where one of the four screws go. Then I chose to mount the Red wire to the "Instrunent Panel Illumination" fuse #31 on my SVT. Then plug in the guages to the other two black wires and use a tie down to hold the control box. Then you can just use the same plug in as the guages for the HVAC.
