A. Mount the Ignition/Boost Control unit above the
radiator shroud using Velcro ® strips (see photo).
B. Route the heavy black cable to a clean ground.
Route the heavy red cable to the battery. Using
a solderless connector, connect the supplied
fuse holder and fuse to the end of the wire. Set
the wire aside for now (do not connect to the
battery).
D. Install the Ignition/Boost Control wiring harness
following the graphic on the next page. Use the
supplied wire and connectors to extend some of
the wires, if needed.
E. Locate the tachometer filter in the factory coil
harness. (Note: 1994 and 1995 models are not
equipped with tach filters. In this case, ignore
step "E".) Cut the thin white wire located near
the filter. Splice the supplied length of wire and
connectors into the thin white wire and run to
the green tach output wire on the Ignition/Boost
Control unit.
F. Mount the timing control knob in an easily
accessible position from the drivers seat. Attach
the black wire to a clean ground and the red wire
to a keyed on 12V power source or the red wire
from the Vortech ignition box. Tape up the end
of the yellow wire to prevent contact with a
metal surface. Route the three-wire harness
out into the engine compartment near the battery.
Connect the supplied GM-style map sensor to
the three-wire harness and secure.
G. Route a vacuum line from the supplied map
sensor to the bypass/vacuum line assembly
using a 5/32" tee.
