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. On GM vehicles the neutral safety
switch may be located on the shifter (steer-
ing column or console), or it may be a me-
chanical interlock in the steering column that
prevents the key from turning to the Start
position unless the shifter is in the Park or
Neutral position. Identify the type of neutral
safety system you have. If the key will not
turn to the Start position unless the stock
shifter is in Park or Neutral, you have a me-
chanical interlock type, otherwise you have
a neutral safety switch type. If you have a
neutral safety switch, locate the switch and
identify the neutral safety wires (engine will
not crank unless these wires are connected
together). With either type, disconnect bat-
tery ground cable to prevent accidental
shorts. If you have a neutral safety switch,
disconnect and extend both wires from the
GM switch to the 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 termi-
nals on the ends of the lengthened wire.
Crimp terminals onto wires using a crimping
tool or pliers. Connect the wires to the switch
on the shifter. Tape terminal connections
and all other connections to prevent shorts.
Reconnect battery ground cable, discon-
nect coil wire and set the parking brake.
Check switch operation by attempting to

Some C-6 and all (late) C-4 and C-5 trans-
missions 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. Disconnect
the switch at the factory plug and discard it.
STEP 16. Install the B&M selector lever,
See figure 6 or 7. Note: The B&M lever
must point downward for proper opera-
tion. If the stock shift lever on your trans-
mission points down, you will have to re-
move the lower part of the stock arm by
start motor in each shifter position. The
starter must crank only when shifter is
in the Park or Neutral position. Adjust
switch if required. Reconnect coil wire. Go to
Step 27.

STEP 15. If you have not already done
so, remove the nut and lockwasher hold-
ing the downshift linkage onto the down-
shift 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. Re-

other two holes for other
