nals onto the wires using a crimping
tool or pliers. Connect the wires to the
switch on the shifter. Tape the termi-
nal connections and all other connec-
tions to prevent shorts. Reconnect the
battery ground cable, disconnect the
coil wire and set the parking brake.
Check the switch operation by at-
tempting to start the motor in each
shifter position. The starter must
crank only when the shifter is in
the Park or Neutral position. Ad-
just the switch if required. Reconnect
the coil wire. Go to step 25.

STEP 13. If you have not already
done so, remove the nut and lock-
washer holding the downshift linkage
onto the downshift lever shaft. The
downshift lever is the outer lever on C-
4 and C-6 transmissions. Pull the le-
ver off the shaft and allow the linkage
to hang free. Remove and discard the
stock shift linkage rods. Some C-6,
C-5 and C-4 transmissions have a
neutral safety backup light switch on
the transmission. If your transmission
is so equipped, remove the two bolts
holding the switch in place and slide it
off the shift shaft. Disconnect the
switch at the factory plug and discard
it.
STEP 14. Install the B&M selector
lever (See Figure 4 or 5). Note: The
B&M lever must point downward for
proper operation. If the stock shift le-
ver on your transmission points down,
you will have to remove the lower part
of the stock arm by cutting it off to
clear the B&M lever (See Figure 4).
Install the B&M selector lever onto the
shift shaft of the transmission. Align
the selector lever so when it points
straight down it travels equal arcs in
both directions from the center, then
tighten the 1/4"-20 x 1 1/2" bolt and
nut. The lever should travel smoothly
from front to back with a positive click
in each gear position. Make sure the
o-ring is in position on the downshift
shaft and install the downshift lever in
position on the shaft. Install the
lockwasher and nut and tighten se-
curely. The downshift lever must oper-
ate smoothly. Reconnect the down-
shift linkage.
STEP 15. Cable bracket installation:
C-4, C-5: Remove the two lower bolts
from the rear servo cover. Install the
cable bracket in position (See Figure
4). Install the two servo cover bolts as
removed and tighten to 12-13 lb-ft. Do
not overtighten as this can distort the
servo cover.
C-6: Remove the two transmission oil
pan bolts from the left rear corner of
the oil pan. Install the cable bracket in
position (See Figure 5) with two spac-
ers between the pan and the bracket.
(If your transmission is equipped with
a cast aluminum oil pan, these spac-
ers can be omitted.) Install the two 5/
16-18 x 1.00" bolts supplied and
tighten to 12-13 lb-ft. Do not over-
tighten as this can damage the pan
gasket.
STEP 16. Route the shifter cable ac-
cording to Figure 2. 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
portion.
STEP 17. Move the transmission se-
lector lever by hand to full rear position
(Low). Place the shifter lever to the Low
gear position, the next to the rearmost
position. Adjust the large nuts on the
cable so that the swivel will slide into
the 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.
With the swivel in the selector le-
ver, move the shifter to the Park posi-
tion, as far forward as the shifter will go
without forcing it. (The shifter has fur-
ther travel that is used to reach the GM
park position but is not used on Ford
transmissions. Trying to force the cable
will damage the cable.) The shift lever
on the transmission should be all the
way forward. Check to see that the
swivel will slide freely in and out of the
hole in the 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 in both the Low and the Park
positions. Operate the shifter through
all the gear positions. Check to make
