Step 17: For the neutral safety switch to function properly, the shifter linkage
must be adjusted correctly. Do not attempt to adjust the neutral
safety switch unless you have completed
Step 15.
The Lokar neutral safety switch is a simple on/off, non-directional
switch. The switch passes current (turns on) when the ball is pushed
in. It does not pass current (turns off) when the ball is out at its
at-rest position.
Loosen, but do not remove, the two 5/16"-24 x 3/8” button head
bolts that attach the right side banana bracket to the switch plate
(the bolts are in curved, slotted holes).

WARNING: Before taking the shifter out of Park, be sure that the
vehicle’s tires are scotched and the parking brake is set to avoid
movement of the vehicle.
Step 18: Put the shifter into the Reverse position.
Step 19: Reposition the switch plate so that the hole in the switch plate
lines up with the center groove in the shifter body. Fig. 12 Screw
the provided aluminum adjuster plug into the neutral safety switch
opening. Wiggling the shifter lever slightly while you are screwing
the adjuster plug in will help get the shifter body centered on the
plug.

Step 20: Retighten the two 5/16"-24 x 3/8” button head bolts that attach
the right side banana bracket to the switch plate.
Step 21: Remove the aluminum adjuster plug, and reinstall the neutral
safety switch and washer onto the shifter. Test for continuity by
connecting an ohmmeter lead to each stud on the neutral safety
switch. When adjusted correctly, you will only have continuity
between the two switch studs when the shifter is in Park or Neutral.
Continuity in any other gear requires readjustment of the neutral
safety switch.
Step 22: Connect the neutral safety switch between your ignition switch and
starter circuits. Check the wiring of your fuse panel:
• If there are (2) connections for a neutral safety switch, run a #12 (or
heavier) stranded wire from these terminals in your fuse panel to
the (2) terminals on the neutral safety switch. That completes the
Neutral Safety Switch wiring.
• If your fuse panel does not have neutral safety switch connections,
locate the wire going from the ignition switch to the starter. If GM
color codes are used, this wire will usually be purple. After locat-
ing the wire, disconnect it from the starter. It must be cut and
routed from the ignition switch to one of the neutral safety switch
terminals, and from the other neutral safety switch terminal to the
same stud on the starter where the original wire was removed. If
the wire must be lengthened, be sure to use wire that is at least
the same size or larger than the original.
Step 23: Reconnect the negative battery cable and check operation. Make
sure that the engine will not start in reverse or a drive gear. If it
does, follow the neutral safety switch adjustment procedure again.
If your car should ever start in any gear other than Park or Neutral,
please readjust the neutral safety switch accordingly. Tighten all
brackets and bolts correctly and securely and there should be no
movement or maladjustment. If you have any questions after follow-
ing this procedure, please call Lokar Technical Support.
Step 24: Once the installation is completely finished and the neutral safety
switch is adjusted, remove each of the 5/16"-24 x 3/8" button head
bolts from the banana brackets one at a time, apply blue thread
locking compound to the threads, and reinstall.
For shifters manufactured 1994 and earlier, please contact Lokar for assistance.

To Install Shifter Knob:
Step 1: Make sure the jam nut is still in place on the shifter lever.
Step 2: Screw the shifter knob onto the shifter lever until the release button
comes up flush with the top of the shifter knob.
Step 3: Tighten the jam nut up against the bottom of the shifter knob.
Step 4: Check to make sure that depressing the release button allows the shifter
lever to be moved, and that the shifter lever still locks in Park and
Neutral. If the shifter will not come out of
“PARK” with the release button
fully depressed, tighten the knob one turn and check it again. If the shift-
er does not lock in
“PARK”, loosen the knob one turn and check it again.
