Pass-Lock Interface
The Pass-Lock system is similar to the Pass-Key system except the resistor is inside the steering column instead of
the ignition key.
1. Locate Pass-Lock wires coming down the steering column. (3 bonded wires)
2. Determine wire color type. Cut the yellow or black Pass-Lock decoder wire.
3. Use a digital ohm meter and connect the red lead of test meter to the cut yellow wire that goes to the ignition
lock cylinder.
4. Connect the black lead of test meter to the orange/black wire.
5. Turn the ignition key on and momentarily crank the engine.
6. Do not turn off the key. Record the reading on your digital meter and turn off the key.
7. Connect the green wire (87a) of ALA-RP1 to the cut wire that goes to the ignition lock cylinder.
8. Connect the purple wire (30) of ALA-RP1 to the cut wire that goes to the Pass-Lock Decoder.
9. Connect one side of correct resistor to the orange wire (87) of ALA-RP1.
10. Connect other side of the resistor to the orange/black or black wire of the vehicle.
11. Verify the vehicle starts OK with the ignition key.
Pass-Lock 1 Vehicle Only (For Older Pass-Lock Vehicles Only)
In addition to the above connections, the first generation Pass-Lock systems will also require the bulb test circuit to
be energized with a ground signal during cranking. This will require an ALA-984H relay.
1. Connect 85 & 30 of relay to ground.
2. Connect 86 of the relay to our orange starter wire.
3. Connect 87 of relay to the vehicle’s black bulb test wire.****
**** The bulb test wire will show ground when the ignition switch is rotated to the start position only. Do
confuse the bulb test wire with the black Pass-Lock wire. Do “not” connect the relay to the black wire that’s in the
3 ribbon wire cable.
