Enlarged version

Most of the 1990-1995 Cadillacs have a slight variation on the wiring for the VATS

system. On these cars, there is an ORANGE wire (actually a vinyl sleeve) that contains

smaller wires. This is located underneath the steering column next to the YELLOW

sleeve that is labeled "Air bag wiring" -- do not cut this Yellow sleeve. Slit the ORANGE

sleeve open to expose two pairs of wires which are either both white, OR both yellow,

OR both black.

Note:

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) Diesel Vehicles:

You must hook the RED/BLACK wire up to the diesel

glow-plug light wire or to the positive side of the vlow plugs itself as described in

STEP 18.

The following chart outlines the options that need to be set for diesel vehicles. (Use

the Chrysler settings for all other diesel vehicles.)

3) General Motors Passlock™ Security System Bypass

New GM PASSLOCK

Anti-Theft System for 1995 through 1997 models

Beginning in 1995 and 1996 GM introduced a new version of their old VATS

security system. This new PASSLOCK

Chevrolet Z24 Cavalier, Pontiac Sunfire GT only, 1996+ Pontiac Grand Am,

Oldsmobile Achieva, and the Buick Skylark, Chevrolet Cavalier and Pontiac

Sunfire. You can determine if the vehicle is equipped with this system by

checking for a "Security" or "Theft" light on the dash panel. Basically, what

they have done is taken the resistor that was part of the key on the original

VATS and moved it to inside the lock cylinder of the steering column. They

have also set additional parameters to make this even more complicated. To

bypass this system, use the following diagram and instructions. Follow these

instructions very carefully and remember that the resistance must be within 5%

of the correct measured value.

Note that for these vehicles with PASSLOCK, the AutoCommand's Green Igni-

tion 2 wire goes to the vehicle's White Ignition wire. The AutoCommand's

White Accessory wire goes to the Vehicle's Orange Ignition wire.

!! WARNING !!

On cars with airbags, you may notice bright yellow tubes or harnesses under-

neath the steering column area. DO NOT tamper with these wires in any way,

so as to prevent personal injury and/or damage to the air bag system.

Battery gases are explosive. Do not smoke while working near the car's bat-

tery.

!!CAUTION!!

When working the wires through the car's firewall, be sure to protect them

from sharp metal edges and from hot surfaces on the engine.

Note:

Some installers connect a battery charger to the vehicle's battery dur-

ing installation. This is fine, but it must be removed before running the ve-

hicle under AutoCommand® control.
