2000 Silhouette Passkey III module

 I have puchased a Directed 555G Passkey III module, I was looking at the wiring diagram yesterday and it look's pretty straight forward except I am wondering about one wire hook up. The direction shows the following;

Pink/black- Ignition (key side)          Purple -Data In/Out

Pink -Ignition (ECM Side)                Black -Ground

Red- +12 Volt Constant                    Green - Key Sense

I have the colors for everything except for the Green - key Sense can any one help me with that color for a 2000 OLDS SILHOUETTE?

Thanks

So it shows 0 volts when the key is not in and 12 Volts when the key is in?      Thanks for the Reply  

Aw yes that works for me, hope to start this project this weekend and better bring my laptop with as I think I will have more questions. I am not a novice at these but I am not a pro either so it nice to have the extra help.

Thanks again.

Ok I just picked up my remote start unit Aolin AL-838SR, I am looking at the wiring diagram (not very good) and here is my first question (not my last one either)I have a yellow tracer wire that goes to a relay to the ignition coil and a Red tracer that goes to another relay to the fuel pump, these also conntect to (2) Brown tracer wires out of the unit, which all so connects to the "ON" on my key switch.  Keeping in mind that this will be installed in a 2000 oldsmobile silhouette, I thinking that these wires do not need to be installed

I figured that I don't have a "ON" on my key but I do have "OFF, ACC & Start".  I know this might not make sense (I could put the diagram on here) but I am trying to work this out before jumping in.  Am I right?
