is pushed to the "lock" position, and the other wire will show ground when the switch is pushed
to the "unlock" position. With the switch at rest, these two wires will read voltage, usually 12
volt positive but in some cases less.
The wires from the switches operate
doorlock relays or a doorlock control
unit with built-in relays. The correct
connection point is between the
switches and the relays.

3 Wire Negative Doorlocks using the AL-100-H Control Unit
3 Wire Positive Pulse Systems are very similar to the Three Wire Negative Pulse system
except the vehicle's doorlock switches use 12 volt positive pulses to operate the vehicle's
doorlock relays or control unit. Examine the three wires on the back of the switch; if more than
three, suspect a 5 Wire Reversal system. One will be constant 12 volt positive, regardless
of the switch's position. Of the two remaining wires, one will show Positive when the switch
is pushed to "lock", and the other will show Positive when the switch is pushed to "unlock".

Type 1 Connection: Meter shows polarity change before the Lock and
Unlock wires are cut. The doorlock relays and RKE unit are also separate.
The Type 2 Connection: When the Gray or Pink wires receive a Positive pulse the
security system will arm or disarm. If the Brown or White wire receive a Positive or Negative
pulse at the same instant
that the Gray or Pink wire receives a pulse, the system will not arm or disarm because the door
switch should not operate the system. The Brown and White wires "learn" the polarity of the
switch wires. Therefore, these wires must rest either at 12 Volts Positive or at Negative
ground.
