Will I need to bypass the Passlcok1 system? I noticed that on my stock radio it had a theftlock LED light on it. I am guessing that means the chip was in the radio. I have had an aftermarket radio for over a year and the car starts fine, I did not have to wire up the anti-theft system when I installed the aftermarket radio, I don't believe.

With Passlock1, there is no transponder chip.  Instead, the ignition key cylinder uses an internal resistance value to generate a

specific voltage that is sent to the vehicles Instrument Panel Cluster for decoding.  If the IPC receives the correct voltage value at the right time, it sends a signal to the vehicles Powertrain Control Module that enables the fuel system.  The Bulldog Securitywiring diagram for your car lists the Passlock1 wire colors and there is a photo of these wires at the steering column. 

There are many Passlock1 bypass modules available.  The Directed 555L, 555LW, 556LW modules are compatible with the 4103

R/S but might be hard to find ( DEI lists them as "Retired" ).    Fortin lists their PASSLOCK-SL2 V2 module and iDatalink has theADS TBSL PL module.   The Fortin and iDatalink modules do not require cutting the Passlock1 resistance wire.  These bypassmodules will cost between $20 and $40.  If you like relays, have a Digital Multi Meter and an assortment of resistors available,you could do it the old fashioned way.  Here is a link to instructions / diagram :  http://documents.audiovox.com/700056.pdf

Soldering is fun!

Thank you for the information. That is very useful! I have some questions about the diagram you may be able to answer. When it says "Black Bulb Check Wire" is that the same as the "Black Passlock Ground Wire"? Also for the "Ignition 2" and "Ignition 3," would I actually be using "Ignition 1" and "Ignition 2" on my remote start... without the relay on "Ignition 3 (Ignition 2 on mine)"?

Also I noticed some other people bypassing the system without relays, they just put a resistor between the yellow and black wire, can this be done as well?
