14. IGNITION/BOOST CONTROL INSTALLATION
(High Output and Cobra systems only)
A. The Ignition/Boost Control unit has been prewired for
installation convenience. Installation is a simple matter
of disconnecting the stock connector at the ignition coil
and plugging in the new adapter. Then plug the stock
connector into the adapter.
B. The next step is to provide a good ground for the black
wire and mounting the box in as cool a place as possible
under the hood. The box should be mounted with the
aluminum cover on the bottom.
C. Using the supplied 5/32" hose and 5/32" tee, connect
the vent on the control unit to the FMU vacuum/pressure
hose
(see graphic at right).
D. Route the Ignition/Boost Control wires through the
firewall from the interior side. Mount the knob in an easily
accessible place.
E. Connect the wires to the plastic oval wiring connector
on the Ignition/Boost Control unit using the snap-on
connector supplied in the Ignition/Boost Control kit.
NOTE: The wiring to the boost/control knob can be
matched to either of the corresponding wires
in the boost retard connector.
10. In the engine compartment, connect the flex hose from
the elbow extending through the hole to the elbow on
the supercharger.
11. Cut the MAF wires 3" to 4" away from the MAF
connector.
12. Slip 1" long sections of the supplied shrink tubing over
each wire before soldering.
13. Using the supplied wiring, solder wire extensions
for the MAF and connector through the fender well.
Position shrink tube over the solder joint and gently
heat until the tube seals the joint.
14. Replace the inner fender lining.
13. AIR FILTER ASSEMBLY, cont'd.
