B&M 80690 MEGASHIFTER - Manual (Page 6)

to over travel into the Park position.
This will move the shifter into GM Park
position and will damage the cable or
the transmission.
STEP 20. On Ford vehicles, the neu-
tral safety/backup light switch is lo-
cated on the transmission (or on the
steering column on some early ve-
hicles). If the vehicle has an AOD
transmission the neutral safety/backup
light switches on the B&M shifter will
NOT be used. The neutral safety/backup
light switch on the AOD transmissions
will continue to function normally.
On the C-4 and C-5 transmissions,
it is necessary to completely remove
the stock neutral safety/backup light
switch in order to install the B&M
transmission shift lever. On C-4, C-5
and C-6 transmissions, it will be nec-
essary to hook up the neutral safety/
backup light switches on the B&M
Megashifter. Locate and identify the
neutral safety (the engine will not crank
unless these wires are connected to-
gether), and reverse light wires. Dis-
connect the battery ground cable be-
fore beginning to wire the neutral safety
and the reverse light switches. Reroute
the wires to the B&M Megashifter .
Strip 1/4" of insulation off the wires and
install the supplied slip-on terminals.
Crimp the terminals onto the wires
using a crimping tool or pliers. Con-
nect the neutral safety wires to the
LOWER switch and the reverse light
wires to the UPPER switch (See Fig-
ure 1). Tape the terminal connections
to prevent shorts. Reconnect the bat-
tery 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
the shifter is in the Park or Neutral
position. Check the backup light op-
eration when the shifter is shifted to the
Reverse position. Adjust the switches
if required. Reconnect the coil wire. Go
to Step 27.

STEP 21.If you have not already done
so, loosen the pinch bolt on the throttle
lever on the transmission. This is the
lever on the small diameter shaft. Pry
the lever off with a screwdriver and
allow the linkage to hang free. Remove
and discard the stock shift lever and
the stock shift linkage. Install the B&M
selector lever in position and tighten
the pinch bolt securely (See Figure
8). Make sure the lever is not pushed
down so far as to touching the trans-
mission case. This will cause the lever
to bind on the case. The lever should
travel smoothly from front to back with
a positive click in each gear position.
Install the stock throttle lever in posi-
tion on the small diameter shaft as
removed and tighten the pinch bolt
securely. The throttle lever must oper-
ate smoothly.
STEP 22.Remove the two transmis-
sion oil pan bolts directly below the
shift lever. Install the cable bracket in
position with the two spacers between
the pan and the bracket (See Figure
8). (If your transmission is equipped
with a cast aluminum oil pan these
spacers can be omitted.) Install the
two 5/16-18 x 1.00" pan bolts supplied
and tighten to 12-13 lb.ft. Do not over-
tighten as this can damage the pan
gasket.
STEP 23. Route the shifter cable ac-
cording to Figure 4. Avoid kinks and
sharp bends and route the cable away
from hot engine or exhaust parts.
Remove the two rubber boots, one
large nut, and a large lockwasher from
the threaded end of the shifter cable.
Slide the end of the cable into the cable
bracket. Install the large nut and the
lockwasher loosely over the end of the
cable. Install the 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
