WIRING A RELAY FOR SECOND OR THIRD IGNITION
NEVER connect two Ignition wires of the vehicle together to avoid using a relay. If the vehicle
manufacturer wanted the Ignition 1 and 2 wires to be summed, they would have done it at the factory!
This is not only unwise because of the current draw issues, but this is a perfect opportunity for the dealer
to call the warranty void if ANYTHING relating to the electrical system goes wrong.

TESTING THE 12V ACCESSORY WIRE:
• This wire is powered when the key is in the accessory and run position.
• This wire will not show 12V during the cranking cycle.
• Most often found in the harness coming from the key cylinder.
To find 12V accessory with a multi-meter:
1. Set meter to DC voltage
2. Attach the (-) probe of the meter to chassis ground
3. Probe the wire you suspect of being the accessory wire with the (+) probe. The steering column harness or
ignition harness is an excellent place to find this wire.
4. Turn the ignition key to the accessory and then the run position. If your meter reads 12V on each, go to the
next step
5. Turn the key to the start position. The meter should drop to zero. If it does, this is the correct wire.
NOTE: Some vehicles have more than one accessory wire that must be energized for the remote start process in
order for the vehicle to run properly. If the system only has one (+) accessory output, use a relay for each
additional accessory wire that must be energized and wire as shown:
