Disconnect both negative battery cables.
Remove the two cap-screws that attach the fuel filter head to the intake manifold, this should allow enough clearance to access
the 50 pin connector.
Locate the 50 pin connector at the ECM shown above. Locate port #20 and remove the sealing plug. Be careful not to push the
plug in.
Insert the black wire of the Pacbrake harness into pin #20 until it stops, then pull gently to ensure the terminal is locked in place.
Using the plastic ties supplied, secure the Pacbrake harness to the Dodge main harness. Be sure to follow Drip Loop in the Dodge
harness when securing the Pacbrake harness.
Reinstall the fuel filter head to the intake manifold.
