switch on the shifter. If you have a mechanical
interlock cut the wire that goes from the start
position on the ignition switch to the solenoid
on the starter. This wire is usually a 10 or 12
gauge purple wire. Run wires from both ends
of the cut wire to the switch on the shifter. Put
slip on terminals on the ends of the lengthened
wire. Crimp terminals onto wires using a
crimping tool or pliers. Connect the wires to the
LOWER switch on the shifter. Identify the
wires for the backup lights and run them to the
UPPER switch on the shifter. Tape terminal
connections and all other connections to pre-
vent shorts. Reconnect battery ground cable,
disconnect coil wire and set the parking brake.
Check switch operation by attempting to start
motor in each shifter position. The starter
must crank only when shifter is in the Park
or Neutral position
. Adjust switches if re-
quired. Reconnect coil wire. Go to Step 27.

STEP 15. If you have not already done so,
remove the nut and lockwasher holding the
downshift linkage onto the downshift lever
shaft. The downshift lever is the outer lever on
C-4, C-5, C-6 and AOD transmissions. Pull
the lever off the shaft and allow the linkage to
hang free. Remove and discard stock shift
linkage rods. Some C-6 and all (late) C-4 and
C-5 transmissions have a Neutral safety/
Backup light switch on the transmission shift
lever. If your transmission is so equipped,
remove the two bolts holding the switch in
place and slide it off the shift shaft. Discon-
nect the switch at the factory plug and discard
it.
STEP 16. Install the B&M selector lever, See
figure 7 or 8. Note: The B&M lever must point
downward for proper operation. If the stock
shift lever on your transmission points down,

with the optional installation kit, Part No. 40496
C-4, C-5: Remove the two lower bolts from
the rear servo cover. Install cable bracket in
position, (See figure 7). Install two servo
cover bolts as removed and tighten 12-13 ft.
lbs. Do not overtighten as this can distort
servo cover.
C-6: Remove the two transmission oil pan
bolts from the left rear corner of the oil pan.
Install cable bracket in position, (See figure 8)
with two spacers between the pan and
bracket. (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" bolts
supplied and tighten 12-13 ft. lbs. Do not
overtighten as this can damage pan gasket.
STEP 18. Route the shifter cable according to

you will have to remove the lower part of the
stock arm by cutting it off to clear the B&M
lever, (See figure 8). Install B&M selector
lever onto shift shaft of transmission. Align
selector lever so when it points straight down
it travels equal arcs in both directions from
center, then tighten 1/4"-20 x 1 1/2" pinch bolt
and nut. The lever should travel smoothly
from front to back with a positive click in each
gear position. Make sure O-ring is in position
on downshift shaft and install downshift lever
in position on shaft. Install lockwasher and nut
and tighten securely. Downshift lever must
operate smoothly. Reconnect downshift link-
age.
STEP 17. Cable bracket installation:
