1. Remove the top and bottom halves of the steering column shroud.
2. Locate the small three wire harness (with White, Black and Yellow wires) running down from the
ignition key cylinder on the top right hand side of the steering column into the instrument panel.
3. Cut the Yellow wire in half and bare back the Black wire.
4. With the ignition key in and turned to the “ON” or “RUN” position, measure the resistance be-
tween the key side of the Yellow wire and the Black wire. Make several measurements to verify
that you have a consistent resistance. You also need to change your test leads around. You will find
that you get two different readings. So far we have found that the higher of the two readings is the
correct resistance.
5. When you have correctly identified the correct resistance obtain a resistance of the same value.
6. Locate the Black “Bulb Test” wire on the left side of the steering column in cavity “D” or “E” of
the Black 5-way connector, just above the main ignition switch connector.
7 . Wire the relay as shown in the following Diagram.
4) New GM PASSLOCK
®
II Anti-Theft System for 1998 model
vehicles.
In 1997 the Malibu/Cutlass and then in 1998 all truck platforms (Full size
Pickup, Suburban, S-10/Sonoma, Blazer/Jimmy, Tahoe/Yukon and Astro/Safari) came out
with this new Passlock II system.
Use the diagram above and the list below to interface to this new type system. Note that the
Yellow wire for the Passlock is a similar gauge wire to the Starter wire. Don’t confuse these.
You must acquire a resistor value within 5% of the value of the resistor in the key. Addition-
ally, there is No BULB TEST wire on this system, so pin 87 is not used.
Substitute as follows:
