switch and the reverse light wires (dark blue
and light green) to the UPPER switch (See
Figure #2). Tape the terminal connections to
prevent shorts. Reconnect the battery ground
cable, disconnect the coil wire and set the
parking brake. Check the switch operation by
attempting to start the motor in each shifter
position. The starter must crank only
when shifter is in the Park or Neutral
position. Check the reverse light operation.
Adjust the switches if required. Reconnect
the coil wire.
Note: Some models will have two additional
wires, orange with black and black with
white going to the plug. Do not join these
wires. Tape the ends of these wires sepa-
rately to prevent grounding. With the factory
shifter, these are switched together in the
Neutral and Park positions. This circuit locks
out the converter clutch and changes the idle
speed. This circuit can be restored by the
addition of the supplied relay operated by the
neutral safety switch circuit (See Figure
#6). The relay is a Double Pole Single Throw
relay for 12 VOLTS DC operation and has a
30 amp rating (minimum one amp required).
STEP 15. Cut the bulb socket from the stock
console light. These wires will be connected
to the indicator light on the shifter. Remove the
indicator assembly from the stock console
cover plate. A small file or a hot knife works
well.
STEP 16. Place the supplied template on top
of the GM console top cover. On the Camaro,
locate the holes marked “A” over the four
stock holes around the shifter opening. On
the Firebird, locate it with the two holes
marked “B” over the stock screw holes. Tape
the template onto the cover plate and transfer
the cutout shape to the cover with a scribe or
felt tip marking pen. Drill 1/4" holes in the
corners of the rectangular area. Cut away a
rectangular area with a key hole saw. File or
sand the edges of the cut.
STEP 17. Install the GM console top cover,
using the original hardware. Feed the B&M
top plate through the hole in the cover.
STEP 18. Install the indicator light bulb in its
socket on the shifter cover plate. Connect the
wires that were cut in Step 15.
STEP 19. Snap the shift position window into
the top plate. The window snaps in from the
top with the tabs inserting into the slots at
either end of the window opening. Place the
shifter in the Park position then remove the T-
Handle from the shifter. Place the cover plate
over the stick and onto the top of the tower.
Route the indicator cable around the front of
the shifter so that it has a free radius and will
not bind. Run the shifter through all of the
gears to check the operation of the indicator.
If the indicator needs adjustment, loosen the
screws holding the indicator cable clamp to
the cover plate and slide the cable bracket to
adjust the indicator position. (Retighten these
screws carefully since they are threaded
into plastic.) Attach the cover plate to the
tower with four Phillips head screws.
STEP 20. Slide the boot over the stick and
install it into the cover plate. Note that the front
the end of the cable. Install two rubber boots
onto the end of the cable. Install the swivel on
the threaded end of the cable and position it
in the center of the threaded portion.
STEP 13. Move the transmission selector
lever by hand to full rear position (Low).
Operate the shifter lever to the Low gear
position (ratcheted all the way back). Adjust
the large nuts on the cable so that the swivel
will slide into the front hole on the selector
lever. Tighten the large nuts completely. Be
sure that the swivel will slide freely in and out
of the hole in the selector lever. Note: The
shifter will not operate correctly unless
the front hole in the shift lever is used.
Leave the swivel out of the hole and move
the selector lever to Park, all the way for-
ward. Also move the shifter to the Park
position (all the way forward). Reinsert the
swivel into the front hole in the selector
lever. Check to see that the swivel will slide
freely in and out of the front hole in the
selector lever in this position. If it does not slip
in freely, adjust the swivel slightly until it will
slip into the hole in the lever.
Move the shifter back to the Low gear
position and check that the swivel will still
slide easily in and out of the front hole in the
selector lever. Operate the shifter through all
the gear positions. Check to make sure the
swivel will slide in and out of the front
selector lever hole in each gear position. The
shift cable is now correctly adjusted. Install
the cotter key supplied with the shifter into the
swivel and spread the key ends.
If you have a problem, DO NOT FORCE
THE SHIFTER, this will damage the cable,
the shifter or the transmission. Simply start at
the beginning and carefully check all your
steps.
STEP 14. Disconnect the battery ground cable
before beginning to wire the neutral start and
reverse light switches. Locate and identify
the neutral start and reverse light wires on the
stock wiring plug removed in Step 4. Cut
wires from plug then strip 1/4" insulation off
the wires and lengthen them with 4-6" of
additional wire. Put slip-on terminals on the
end of the lengthened wire. Crimp the termi-
nals onto the wires using a crimping tool or
pliers. Connect the neutral start wires (the
purple and yellow wires) to the LOWER
