I knew about that part. The switch circuit is isolated, which makes total sense to me. The yellow is for the switch, and goes to the ignition line as you say. However, the whole point is, I'm trying to eliminate the connection to the ignition line alltogether. PassKeyII utilizes the voltage, and any tiny change in it tells the car "This isn't the right key, don't start." I could be wrong about this, but I don't want to even try being wrong. I guess to re-word the question better, is there a constant-on line I can connect to somewhere, and just throw in an STSP between it and the sensor line? Perhaps an even better question is, what exact voltage needs to pass through the sense line to trigger the timer?

Where Orange is some constant-on that is not the ignition, yellow is the switch, red is the +, and black is the ground. So, textually, the circuit for the power would be as follows:
Battery -> Fuse -> DPST Switch -> Opus -> DPST switch -> Battery
Then the sensor circuit would be as follows, (Again, textually),
Constant-on line -> SPST Switch -> Opus
Does this seem right? One switch for a hard-on/hard-off function for when the car is not in use for extended periods of time, and a switch for soft-on/soft-off functions as well.
And while I do admire your MS paint skills, them being significantly better than mine (as I've clearly demonstrated, I suck.), I'm reasonably certain that the "On" position is considered "closed" in an electrical environment, while the "Off" position is considered "open" in the same environment. An open circuit is not completed, therefore power cannot flow, and a switch is off. A closed circuit is when the whole circuit is complete, power can flow, and the system is therefore on.
BTW: Shirley is all the way in the middle of Suffolk County, exit 67, 68, and 69 on the LIE.
Quick Edit: The red box in the MSPaint drawing is the fuse/fuse holder. Only the word "Fuse" made it in.
