THis is what you need to know..

BLAZER 1998-2003
WIRE COLORS LOCATION
12 VOLTS CONSTANT RED IGNITION SWITCH HARNESS
IGNITION 1 PINK (+) IGNITION SWITCH HARNESS
IGNITION 2 WHITE (+) IGNITION SWITCH HARNESS
ACCESSORY/HEATER BLOWER ORANGE (+) IGNITION SWITCH HARNESS
STARTER YELLOW (+) IGNITION SWITCH HARNESS
PARKING LIGHTS (+) BROWN LIGHT BLUE Plug at the BCM, See NOTE*
DOME LIGHT NOTE** LIGHT BLUE Plug at the BCM, See NOTE*
POWER DOOR LOCK LIGHT BLUE BROWN Plug at the BCM, (TYPE "A") See NOTE*
POWER DOOR UNLOCK WHITE BROWN Plug at the BCM, (TYPE "A") See NOTE*
TRUNK/HATCH RELEASE BLACK (-) PURPLE Plug at the BCM, See NOTE*
TACH SENSOR WHITE at the PCM See NOTE**
BRAKE WHITE (+) at STEERING COLUMN HARNESS
HORN BLACK (-) at STEERING COLUMN HARNESS
FACTORY DISARM LIGHT GREEN (-) PURPLE Plug at the BCM, See NOTE*
FACTORY ANTI-THEFT PASSLOCK 2 Requires part #791 bypass module


NOTE* The BCM (Body Control Module) is located to the RIGHT of the Gas Pedal below the radio, the Plugs face towards the drivers side of the vehicle.

NOTE** The DRIVERS door is triggered by a TAN (-) wire in a PURPLE Plug, Pin B4, the PASSENGER door is a ORANGE (-) wire in a PURPLE Plug, Pin B4. The REAR doors and REAR hatch is the DARK BLUE/WHITE (-) wire in a LIGHT BLUE Plug, Pin B11. When connecting to an Alarm System you MUST use all 3 wires and DIODE ISOLATE. For DOMELIGHT SUPERVISION use only the TAN (-) wire in a PURPLE Plug, Pin B4.

NOTE** The PCM (Power Control Module) is located on the Passenger side fender. On the 2.2L engine the TACH wire is in a BLACK 80 Pin Plug, Pin 10 and on the 4.3L engine the wire is in a RED 32Pin Plug, Pin 20.

i got it work ,it starts but it shuts off with the remote starter is it because i need by-pass module ???
the security light blinks to when you try to start it with the remote

MT might have forgotten about this old post of his, you know how it goes as you get older:

The following is a procedure to disable Passlock I or II Systems for vehicles in which remote start/stop system installations are required. This procedure is required because a remote start system will not function with the current Theft Deterrent System (Passlock) which is included on many 1996 and up GM vehicles.

Please note that this modification is intended to be used only in conjunction with the installation of a remote start/stop system and does not provide a procedure to install a remote start/stop system.

CAUSE
If an attempt is made to start a vehicle by a means other than a key rotation in the ignition switch, the Body Control Module (BCM) will interpret this start as a vehicle theft and disable the fuel injectors.

CORRECTION
A minor wiring modification may be made to allow the vehicle to be started remotely. This modification includes adding a switch to allow the customer to select “ON” to disable Passlock or “OFF” for normal Passlock operation.

CAUTION: When this modification is performed and the switch is set to the ON position, the theft deterrent feature will be disabled. When the theft deterrent is disabled the SECURITY or THEFT telltale will light up indicating that the theft deterrent system is NOT functioning.

PASSLOCK MODIFICATION
Refer to appropriate GM service manuals and/or SVMQP Electrical Guideline Manual for instruction on splicing and electrical connections.
1. Select a suitable on-off switch (see note below) which will be used to disable/
enable the Passlock System. Mount the switch in a location such that it is
accessible to the driver and will not interfere with normal vehicle operation.
NOTE: This is an extremely low current circuit (approx. 7mA), it is therefore very important that a high quality, low energy, fast acting switch be utilized
for this application.
2. Turn the ignition switch to the OFF position.
3. Locate the Main Ignition Switch Harness. GM's Passlock System wires exit the Ignition Switch Tumbler together and then join with the Main Ignition Switch Harness. (See http://www.bulldogsecurity.com/ or http://64.85.6.118/diagrams/diagrams.asp and select your Make, Model and Year for wire colors and clues on the quickest way to access these wires.)
4. Locate the Yellow Passlock Data Wire which is included in a bundle of three tiny (20 GA) wires wrapped in friction tape.
Cut this wire and splice a 0.5mm2 (20 GA) yellow wire to each end of the cut wire.
Keep wire length to a minimum. Route modification wires clear of moving parts.
Connect the yellow wires to the switch such that the contacts are OPEN when the switch is in the ON position.
5. Turn modification switch to the OFF postion (contacts closed).
6. Start vehicle to verify normal operation. If engine “cranks but will not start"
recheck the switch position (contacts should be closed), wire connectors and
modification wiring.

SWITCH OPERATION

To enable remote start:
Start the engine with the ignition key (modification switch must be in the OFF
position). Turn modification switch to the ON position (contacts open). The
SECURITY or THEFT telltale will light up indicating that the Passlock System is inoperative.
Once the SECURITY or THEFT telltale has been on for at least 5 seconds the vehicle can be turned off and then remotely started.

To disable remote start:
The Passlock System can be reactivated by turning the modification switch OFF
(contacts closed). Vehicle can either be running or off when this is done.

Please note that the VCM/PCM will record Diagnostic Trouble Codes (DTCs) related to the security system when the modification switch is in the ON position (circuit open). This is due to the way that the VCM/PCM interprets this condition.

NOTICE
Any condition which removes battery power from the Vehicle Control Module/Powertrain Control Module (VCM/PCM) (e.g. dead battery, disconnected harness connectors, etc.) will prevent the vehicle from being restarted. If the engine exhibits a “cranks but will not start” symptom, place the modification switch in the OFF (contacts closed) position. This will reactivate the Passlock System and allow the vehicle to be started with the ignition key.

I'm not sure what you mean by "bypass module". On my 98, I had to wire in a relay and a variable resistor to mimic the resistance of the PASSLOCK II module. I did not know about this On-off switch option at the time, it sounds a little easier to do.

The PASSLOCK wires are very small, I know one was yellow, I don't remember the color of the other. If you still need it, I could take a look under my dash tomorrow, I should be able to see those pretty easily.

For Passlock II:

Orange/Black: Ground Reference
Yellow: Resistance
