Route the red and black wires along with the

r.)
Attach the ground from the relay and the
Paxton engine management unit to the same
stud. Connect the red wire from the fueler to
terminal 87 on the relay. Route the wires
from the relay back toward the fuse box.
Using the supplied blue shrink type butt
connector, splice the green wire into the
green wire with the black stripe. (See
Fig.
3-15
.) This will be the trigger for the relay.

Using a heat gun or lighter, apply heat until

*****DURANGO ONLY*****
Engine Management installation, please refer to assembly
drawing #1017718. This shows the pin locations and
correct connector on the factory ECM. Mount Paxton’s
Engine Control Unit to the cover of the power distribution
box in the engine compartment. Route the 8-wire har-
ness across the firewall of the engine compartment to
the factory ECM. Locate the black connector on the ECM
and strip back enough of the factory tape and split loom
to allow locating the pins and colored wires in the factory
harness. Make your cuts in the harmess approximately
2” to 3” from the plug to the ECM. This allows working
room to make the connection from the Paxton supplied
Engine Management Unit to the factory ECM. (Although
Paxton supplies 8 butt connectors in the kit to make the
connections between the Engine Control Unit and the
ECM we recommend you solder the connection in place
of the supplied connectors, assuring a good connection.)
If you use the connectors, be sure to carefully crimp
them to make a good connection.
u.
Route the injector harness straight across
and over the engine. Connect to the two
injectors in the discharge tube.
v.
Re-install the fan shroud and re-connect all
electrical connections. Install the supplied
90°. rubber elbow on the washer pump dis-
charge port nearest the dual idler pulley. Re-
connect the remaining pump as stock. (See
Fig. 3-17.
)

y.
Install the air intake assembly. Connect the
“S” shaped hose to the small hose barb.
Connect the compressor bypass to the larger
hose barb and secure.
z.
Refill the radiator with coolant.
Congratulations - you are done.
