firewall and install the relay receptacle and relay ground wire 
on this bolt.
Install relay into the receptacle.

Ford installs a brake pressure applied switch on the front 
lower side of the master cylinder. 
Locate the black wire with a yellow stripe. Cut this wire and 
crimp on the two red terminals provided. Connect these to 
the mating terminals of the two remaining blue wires coming 
from the relay harness. 
Neatly secure all wiring with the plastic ties. Connect the 
wiring harness to the solenoid and to the cruise relay.

Remove the lower instrument panel (see arrow). Drill a 1/2” 
hole as shown for the dash switch. The dash switch location 
is a suggestion only. 
Install the Pacbrake on/off switch. Connect the two wiring 
harnesses to this switch, observing the correct wire and 
terminal locations as shown in the wiring schematic.
Switch location can vary depending on customer choice or 
the availability of space. Choose a location which is conve-
nient to the driver. Pacbrake offers a transmission gear lever 
mounted on/off switch for manual transmission equipped 
vehicles.

Locate a 12 volt ignition power source in the harness directly 
below the steering column (see arrow).
Attach the yellow T-tap connector to this wire which should 
be 12V+ ignition switched.
