Notes:

NOTE: This vehicle has the passlock II immobilizer system that, when adding a remote start, must be interfaced with. Use DEI part 555t or 555L.  *1 Remove the radio, without unplugging it, to access the ignition harness.  *2 Lock requires a negative trigger, and unlock requires a negative trigger through a 1,500 ohm resistor. Must use relays. Must close doors to lock with a single pulse.  *3 Requires a high current ground. Use a relay.  *4 The lt. GREEN/ black is located in the drivers kick and catches only the drivers door. The lt. blue is located in the harness coming from the drivers running board going under the drivers seat and it catches all other doors. Use both door trigger wires and diode isolate each. On the 2 door the lt.blue is in the passenger kick.    *5 The ECM is located under the left side of the dash to the left of the column.

you can use a 555l or you can look on this site on how to do it with a couple of relays. if you dont bypass it your car wont start when you hit the remote. you can get the ingiton wires under the dash too but you still have to pull the radio out to ge the passlock wiring

Radio Shack doesn't make Passlock bypasses. The 555L is a piece made by DEI www.directed.com. It should be $40 at any DEI dealer. Or use the Audiovox AS-GM4. You can also get bypass pieces at www.transponderbypass.com.
