Special Cases - DesignTech AutoCommand 20022 Installation Manual

POWER & IGNITION WIRES
The AutoCommand® module will be installed under the dash once all wiring
has been completed. Do not mount the module at this time! You will need
to check the diagnostic light (LED) as the installation progresses. Locate
(or drill) a hole in the firewall to run the VIOLET (hood) and the GREEN
(tach) wires of the Control Harness and the PINK wire of the Power Harness
through into the engine compartment. The remaining short wires stay in the
passenger area. Leave about a foot of the wire harness under the dash for ease
of working and visual access to the diagnostic lights.
Note: Always connect the Black and Pink wires before connecting
any of the other wires.)
2. Black Wire (14 AWG)
Connect this BLACK wire to a very good, clean chassis ground in the driver's
kick panel area. Use the small red ring terminal if needed. The metal bracing
around or beneath the dash board is not adequate.
3. Pink Wire (12 AWG)
Plug this wire onto the spade terminal marked Power. Run the other end
of this wire through the firewall of your vehicle and to the positive side of
the vehicle's battery terminal. Connect the ring terminal of the fuse
holder provided to the vehicle's positive battery post. Join the remaining
ends of the power wire together by soldering them. Alternatively, you
may wish to use a Yellow butt terminal, but we recommend soldering.

C. You can choose the next option by pushing the left button again to
index to the next option. When you get to the next option you
want to change, simply repeat Step B above. After six seconds,
the AutoCommand® automatically exits the programming mode
(Three LED flashes).
D. Turn the Control Switch back ON and confirm that the LED flashes
once as the switch is turned ON.

SPECIAL CASES

1) VATS system (for GM cars with special PASS key).
If you have a GM vehicle with a factory anti-theft system (a resistor in the key),
you need to follow these directions:
Measure the resistance of the key. It should be between 392 ohms and 11,800
ohms. To do this, put the ohm meter probes on each side of the key pellet.
This value should be close to one of the following (all values in ohms): 392,
523, 681, 887, 1.13K, 1.47K, 1.87K, 3.01K, 3.74K, 4.75K, 6.04K, 7.5K, 9.53K,
11.8K. Purchase a resistor with a value within 5% of this measured value and a
30 amp BOSCH type relay.
Locate the pair of VATS wires (sometimes White/Black striped and Purple/
Black striped) running behind the dash from the passenger side to the driver's
side behind the key switch. Connect our Ignition 2 (GREEN) wire to pin 86
and ground to pin 85 on the relay. NOTE: You will have to use IGN 1 to power
up all of the Ignition wires behind the key -- since IGN 2 needs to be used here
for the VATS relay. Cut ONE of the VATS wires and connect the key-switch
side to NC pin 87A, and the other side (Engine Side) to common pin 30. Connect
the other VATS wire to NO pin 87 with the selected resistor soldered in line as
shown here:
