Type B: Three-wire (-) pulse controlling factory lock relays
This system is common in many Toyotas, Nissans, Hondas, Saturns, and almost all newer Fords with keyless
entry systems. Use your vehicle specific wiring information to locate this wire. If you cut the wire and the locks
stop working, then you are on the correct wire.

Important: If your locks operate in the reverse, (lock when pressing
unlock, and unlock when pressing lock) then switch the lock/unlock wires.
Type C: Direct-wired reversing polarity switches
Interfacing with a reversing polarity system requires either two relays OR one DEI 451M (not included).
It is critical to identify the proper wires and locate the master switch to interface the door locks properly. This
door lock system will be referenced on our vehicle specific wiring information sheet as a "5wi" system.
Locate wires that show voltage on lock and unlock. Cut one of the suspected wires and check operation of the
locks from both switches. If one switch loses operation in both directions and the other switch operates in one
direction only, you have located one of the target wires. The switch that lost all operation is the master switch.
If one switch works in both directions and the other switch works in only one direction, you have a Type A
system. If both switches still operate, but one or more doors has stopped responding entirely, you have cut a
motor lead. Reconnect it and continue to test for another wire. Once both wires have been located and the
master switch has been identified, cut both wires and interface as shown in the following diagram.
