Neutral Safety Switch Adjustment and Wiring

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 16.

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.

Double check to make sure that the bolts in the slotted, curved holes on the

left side of the floor mount mounting bracket are tight. Fig. 5

Step 18: Remove the neutral safety switch and washer from the right side of the

shifter using a 7/8" wrench or socket.

Step 19: Loosen, but do not remove, the two 5/16"-24 x 3/8" button head bolts that

attach the switch plate to the right side of the floor mount mounting bracket

(the bolts are in curved, slotted holes).

WARNING: Before taking the shifter out of Park, be sure that the vehicle’s tires

are blocked and the parking brake is set to avoid movement of the vehicle.

Step 20: Put the shifter into the Reverse position. Reposition the switch plate so that

the hole in the switch plate lines up with the center groove in the shifter

body.

Fig. 17 Screw the provided aluminum adjuster plug into the neutral

safety switch opening. Wiggling the switch plate slightly forward and back

while you are screwing the aluminum adjuster plug in will help get the shifter

body centered on the adjuster plug.

Step 21: Retighten the two 5/16"-24 x 3/8" button head bolts that attach the right

side of the floor mount mounting bracket to the switch plate.

Step 22: 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 or the shifter.

Step 23: 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 locating 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 24: 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 following this

procedure, please call Lokar Technical Support.

Step 25: 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

slotted, curved holes in the floor mount mounting bracket one at a time,

apply blue thread locking compound to the threads, and reinstall.
