Compustar Remote Start Problem

Hi, I just had the Compustar 2W900FMR installed at a local shop and I'm having an odd problem with the remote start.  In the mornings (when the car has been siting for several hours), it works fine.  But if the car is warm (as in having been running recently), the autostart doesn't work.  It cranks up, (the starter seems to run on for longer than normal) and then engine runs for 2-3 seconds and then shuts itself off.  It repeats this 2 more times and never properly starts.  The installer says it's because I need to install an Immobilizer Bypass Module, but when I went to have another key made the dealership told me I didn't need a key with a chip in it because my car doesn't even have an Immobilizer system!  Anyone know why this could be happening?  The installer should have known this wasn't the problem since it  works perfectly when the engine is "cold".  Obviously my installer's troubleshooting skills are lacking, so any info you guys can give me to point them in the right direction would be greatly appreciated.  The vehicle is a '99 Toyota 4Runner SR5.

One other question.  They also said I need to have a pin switch installed for the trunk sensor to work.  Does anyone know if this is true?  The wiring diagram they are using says there is no dedicated (-) Trunk Pin wire in the car and that it uses the same wire as the doors, but it doesn't and I've seen several diagrams on this site that say there a dedicated wire (Light Green\Red - ).  Shouldn't they be able to use the existing pin? If you know for sure, let me know.

I thought it might be related to that, but I'm not exactly sure how the tach sensing is supposed to operate (or what it is supposed to do).  Can you explain how it's supposed to work and how to learn it?

As for the trunk\rear hatch, they did tie into the door triggers initially, but obviously they didn't test it since the trunk doesn't trigger the alarm.  It appears to have it's own trigger, but since it's not on the diagram they are using, they can't find it.

I show the Immobilizer ByPass is available. 

So it sounds like re-learning the tach when it's warm is the way to go.  Are there instructions for this somewhere?  I can ask the installer to do it, but my confidence in them is low..

I'm pretty sure they tapped into the dome light, and the rear hatch doesn't trigger the main dome light since it has it's own.  I asked if they could attach to the rear dome light, and he said he couldn't since there was no ground wire to it...  Anyway, I've seen two different wires mention on this site and I'm not sure which one is right, maybe both?  One is the blue/white that mo12v mentioned above and the other is a Light Green\Red that is supposed to be in the driver's kick panel.  Anyone know which is correct?

One more question.  Does the Compustar have an independent module for shock sensing? Or is the sensor part of the brain? And is it possible to add aditional shock sensors? (it seems to be sensitive enough at the front of the vehicle, but I can't trip the first stage at the rear of the vehicle)  OK, that was more than one question, but at least they were related.  :)
