TYPE #1: 3-WIRE NEGATIVE TRIGGER TYPE
• This Is The Simplest Of All Door Locking Systems. If You Were To Look At The Door Lock/Unlock Switch In The
Driver’s Door It Would Have 3 Wires Coming Out Of It. (A Lock Wire, An Unlock Wire, And A Constant (-) Negative
Ground Wire)
• The Lock & Unlock Wires Will Show A (-) Negative Ground Pulse Only While Actually Locking And Unlocking The
Doors, Otherwise They Will “Float”.
• The LOCK Command Will Be A (-) Negative Pulse.
• The UNLOCK Command Will Be A (-) Negative Pulse.

** SPECIAL NOTE FOR TOYOTAS:
Many Toyotas Have A Child-Safe Door Locking System. If The Vehicle Doors Are Locked By The Unit, Then The
Unit CAN UNLOCK The Doors. But If The Vehicle’s Doors Are Locked With The Vehicle Door Lock/Unlock Switch,
The Unit Will NOT Be Able To Unlock Them. This Happens Because The Vehicle Switch Sends A “Lock-Out”
Command Disabling The Door Locking system.
The Solution Is Very Simple And Only REQUIRES 2 DIODES. Both The Vehicle UNLOCK WIRE And The CHILD-
SAFETY WIRE Must Be Pulsed With A (-)Negative UNLOCK Pulse At The Same time. This CHILD-SAFETY Wire can
Be Found In the Same Plugs That The Regular LOCK & UNLOCK Wires Are Located In.
