I'm attempting to install a designtech model no.  23926 remote starter on a friend's 2003 Saturn L300.  I have taken the panel below the steering wheel off and the plastic around the steering wheel off.  On the driver's side of the steering wheel I found 2 plugs, a black one and a gray one.  I'm assuming that this is the ignition wire harness.  From the designtech website I got the wiring colors.  I can find the basic wires(ign1, ign2, start, acc).  My question is...... it says I need to connect the KEYSENSE wire to Ign 3 on the starter.  Is this wire in the harness itself?  I see a green wire and another wire on the passenger side of the steering wheel but am not sure what it is for.  Also, it says that this vehicle has PASSLOCK II security.  Are these wires in the main harness too?  Are they smaller than the others?  I have installed several remote starters before but not on anything this new.  Anybody know where I can get a wiring diagram for the ignition harness for this vehicle?    Thanks in advance.

So, are the PASSLOCK II wires in the ignition harness itself? And are they smaller than the others?
