Figure 5-10 EFI Wire Harness for Model 490000.
a. Adust wire harness as necessary, so
that ignition coil, MAP/MAT sensor, and
fuel injector connectors and conduit are
positioned below the fuel rail.
b. Draw out harness until ECM J1 and J2
connectors are seated at top of cylinder
1 valve cover and fuse/relay block is
next to voltage regulator.
c. Draw out harness, so that 6-place (or
8-place) engine to chassis connector,
starter solenoid ring and spade termi-
nals, and ground wire ring terminal run
under cylinder 1 heat shield to area of
starter motor and oil fi ll tube.
d. Feed CKP sensor, fuel pump module,
and oil pressure switch connectors and
conduit under intake manifold (at point
of cylinder 1 fuel injector), and then up
between fuel rail and air intake elbow to
outboard side of CKP sensor bracket.
e. Route fuel pump module and oil pres-
sure switch connectors and conduit
through opening at back of cylinder 2
heat shield to area of fuel pump mod-
ule.
