5 Wire Reversal Rest At Ground Systems
differ from the Negative and
Positive Pulse systems as there are no relays or doorlock control unit. In this type
of system, the switches themselves supply the positive voltage directly to the
doorlock actuators, and, more importantly, provide the return ground path. The
important thing to remember is the wires in this system rest at ground, which means
that the wires must be "opened", or cut, to make the connections.
Examine the wires on the back of the switch. Normally five wires will be found-
one will be constant 12 volts positive, regardless of the switch's position; two wires
will be grounded regardless of the switch's position. Of the two remaining wires,
one will show 12 volts positive when the switch is pushed to "lock", and the other
will show 12 volts positive when the switch is pushed to "unlock".

Cutting only one of two wires can cause
misleading test results. For example, if
only the “lock” wire is cut, the “switch”
side of the cut will show (+)12 Volts when
the primary switch is pushed to the "lock"
position and the “motor” side of the cut
will show (+)12 Volts when the primary
switch is pushed to the "unlock" position.

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".
CONNECTION:
Several options are available for connecting to 3 Wire
Positive Pulse doorlocking systems- the DLP-P3 polarity reversal interface, the
DLS and two relays or the DLR-C or DLR-U. If driver's door unlock priority is
desired, use the optional DLS-3. The following diagrams show how to connect
either of the optional DLP-P3 or the DLS and 2 relay interfaces.
