Neutral Safety Bypass Loop (Push-to-Start)

VAIS TECHNOLOGY IS NOT RESPONSIBLE FOR ANY MODIFICATIONS MADE TO VEHICLE SAFETY EQUIPMENT.

The neutral safety switch needs to be activated so you can start/stop the vehicle.

When the vehicle is in park or neutral,
SEER will allow the engine to be started/stopped.

When the vehicle is in Drive or any position other than Park or Neutral,
SEER will NOT allow the engine to be started/stopped.

Classic Cars with Carbureted Engines

In most classic cars when the gear shift is put into the park position the starter wire will switch to a negative (-) signal.

USE A TESTER TO VERIFY IF THE FACTORY STARTER WIRE BEHAVES THIS WAY. IF SO, NO CHANGES IN THE HARNESS NEED TO BE MADE.

If the factory parking position position switch is broken, see the diagram below to replace it.

Locate the 12-Pin connector at the mid-point in the main harness.
Cut the purple wire closest to Pin #5 and Isolate the unused section of wire coming out of Pin #5.
You can also remove the terminal if you don’t want to cut the wire.
Leave the Purple wire going into Pin #4 connected and introduce your parking position signal.

YOU MUST PERFORM THE ACTIONS BELOW FOR ENGINE START/STOP TO WORK PROPERLY!

In most modern car engines, the parking position signal is dedicated, and separate from the starter wire.

Locate the 12-Pin connector at the mid-point in the main harness.
Cut the purple wire closest to Pin #5 and Isolate the unused section of wire coming out of Pin #5.
You can also remove the terminal if you don’t want to cut the wire.
Leave the Purple wire going into Pin #4 connected and introduce your parking position signal.
