INSTALLATION ADDENDUM
Some vehicle operators prefer the Pacbrake dash switch provided in this kit not be installed.
Not installing the dash switch will apply the exhaust brake everytime the throttle is released.
If your customer requests the Pacbrake dash switch not be installed, connect the brown and green
wires of the switch harness togetherusing the connector supplied (see shaded area). Discard the black ground wire.

INSTALLATION ADDENDUM
Some vehicle operators prefer the Pacbrake dash switch provided in this kit not be installed.
Not installing the dash switch will apply the exhaust brake everytime the throttle is released.
If your customer requests the Pacbrake dash switch not be installed, connect the brown and green
wires of the switch harness together using the connector supplied (see shaded area). Discard the
black ground wire of the dash switch.
