02 Sequoia Remote Start Alarm install

U might check your 1st & 2nd Unlock to see if they are Not reversed....

I am 100% sure that the unlock output and stage 2 unlock output are routed correctly to each door.  But, I'm looking back over DEI's document 1070 ( http://directechs.com/techtips/pdfs/resources/security/directed_techtips/1070.pdf) and I think that you maybe right on the lock detection in driver door.  The second stage unlock wire (in passenger door) DOES turn OFF the honking factory alarm when I hit the arm/disarm button a second time to unlock stage 2 (the rest of the doors).  This is likely the reason why stage 1 is causing the factory alarm to trigger, because I did NOT diode and interface the stage 1 UNLOCK wire to this "lock detection" wire.

How about the remote start though?  The car is sitting out back right now, and if I hit the remote start button, the lights flast twice to confirm that the system received the remote start command from the remote control and as soon as the ignition powers on (a few seconds before cranking the starter), the factory alarm starts honking.

I did wire the 555x keysense output wire to the Toyota YELLOW /GREEN keysense wire (@ ignition) and it has the remote start INPUT wire so that it knows when to ground this wire AND send the transponder signal to the factory immobilizer, but though the car WILL remote start (confirming that it has successfully learned the transponder code), it doesn't seem to disarm the factory alarm first.

Thanks for the tip on the driver door.  I was aware of such a wire, but didn't put two and two together to realize that the passenger door after market connections not only unlocked all the doors, but also turned off the factory alarm... MOST LIKELY with THIS lock detect wire.

Thanks a ton for the suggestions guys.  I was able to get everything addressed today.  I guess the gods smiled upon me or something.  Got more done today than the past three days combined.

The driver door needed to be wired to ground unlock wire and "lock detection" wire simultaneously.  This was kind of obvious and I should have gotten that a LONG time before now.  A little embarrassing.

The remote start problem was that I had to use a third ignition (status out) instead of the remote start output because the remote start would send signal briefly before cranking the starter, but would NOT power the 555x DURING the entire cranking process.  I think what was causing the factory alarm to sound was the fact that since the 555x was not getting ground on remote start wire the WHOLE time, it was not grounding the keysense wire the whole time. 

I believe that cranking the ignition and starter while keysense wire is NOT grounded = set off factory alarm.

Regardless, it's all good now and I greatly appreciate all your helpful suggestions.  I guess I'm saying thanks for helping JUMP start my brain... it was pretty fried from working on this project for a couple hours a day over a couple weeks.  Rain has not been my friend during this install!  ;)
