Under the hood, beside the fuel filter, locate the factory 3 pin
Weather- Pac connector on the driver side of the engine (
shown
by the arrow
). Remove the protective cap and install the mating
connector in the Pacbrake harness. Install the removed protective
cap on the unused connector on the Pacbrake harness - unless
you have a performance module connected to it. If so, it connects
to the Pacbrake connector.
NOTE:
Some 1999 model year trucks and all 1998½ will require
the use of a 3 pin triangular jumper harness to connect to the data
link connector. See schematic pertaining to your kit #, found on page
9-11. Proceed to Step 10.

Attach the orange wire to the harness side of the orange/black wire.
These connections are done using the supplied red heat shrinkable
butt connectors.
Locate the brown wire in pin 21 of the C2 connector. Cut this wire and
splice the blue wire of the Pacbrake harness into it using the supplied
red heat shrinkable butt connectors.
C3 CONNECTIONS
Locate the orange/white wire in pin 13 of the C3 connector. Cut this
wire and splice the yellow wire of the Pacbrake harness into it using
the supplied red heat shrinkable butt connectors.
Using the heat gun, heat the connectors to provide a water tight seal
on all heat shrinkable butt connectors. See the wiring diagram
pertaining to your kit #, found on page 9-11.
