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.
