When installing a GM vehicle with a VATS bypass system, the GREEN
IGN 2 wire must only go to the VATS relay. If you need IGN2 in the
car, simply supply power to the IGN2 wire of the vehicle by jumping
power from the BLUE IGN1 wire. (Thus BLUE will be powering up
2 wires behind the key -- and in some cases 3 wires).

2) New GM Pass Lock System
For 1995 and 1996 GM has introduced a new version of their old VATS se
tem. This new PASSLOCK

dash panel. Basically what they have done is taken the resistor that was part
on the original VATS and moved it to inside the lock cylinder of the steerin
They have also set additional parameters to make this even more compli

measured value.
1.
Remove the top and bottom halves of the steering column shroud.
2.
Locate the small three wire harness (with White, Black and Yellow wire
down from the ignition key cylinder on the top right hand side of th

3.
Cut the Yellow wire in half and bare back the Black wire.
4.

When you have correctly identified the correct resistance obtain a resist
