62. When you are fi nished cover the wires and con-
nectors with the piece of split loom supplied.
Route the new extended harness with the tie straps
supplied along the vehicle harness to the fi rewall and
over to the rear of the right (passenger) side cylinder
head. You will be instructed to connect the harness
to a new IAT sensor in a later step. Replace the MAF
and tighten its mounting clamp securely. Re-install
the MAF electical connector.
63. Install the IAT sensor (supplied for LS2) into its
location at the right rear corner of the supercharger
manifold. (Fuel rail and injector removed for clarity.)
Apply a small amount of the supplied grease to the
body of the sensor. Lift the manifold bolt and retain-
ing bracket to slide the IAT sensor into the mounting
grommet.
64. Push the IAT sensor down fi rmly into location.
61. Using the new Intake Air Tempeture (IAT) har-
ness and crimp/shrink connectors supplied, connect
the white 62”wires to either white wire of the new IAT
harness. Strip about ¼” of insulation from the ends of
the IAT harness, then crimp the connectors on. Using
a heat gun or blow dryer set on HIGH; shrink the insu-
lation on the connectors so that it contracts around the
wires completely. You must shrink the insulation, as
crimping the connectors alone is not enough to secure
them!
