IMPORTANT! Before beginning the installation, make sure
that you are connecting to the correct type of Passlock
system (either Passlock I,Passlock II or alternate). You
can determine which type of system is being used by referencing the Vehicle Application Guide section in this
manual.

Unlike the Passkey system, Passlock must detect the correct R-Code
at the correct time. The Passlock I system uses a bulb check wire
to activate the IPC module. This wire is not present in the Passlock
II system. In the Passlock I system, the bulb check wire is
