3) Relay
The relay will be installed in the rear of the car by the fuse box. It has 4 wires, red
with an O-ring goes to the power lug, long red wire goes to red spade terminal on
controller. Gray goes to trigger on fuse box. And black goes to ground. I used one of
the subwoofer box studs to secure it in place.
Gray attaches to the yellow fuse using the supplied “tap” with gray wire. Some shops
will prefer to install the PAC controller in the rear of the car, in my example I installed it
under the drivers side dash. This is personal preference. These instructions pertain to
doing the install under the drivers side dash. Wiring is the same.
At this point relay is now wired and the red wire is run through the back drivers side
and down the rocker panel. The panels simply unsnap on the C7 making it easy.
