doing the python remote start and alarm system having problems with the addition of priority door unlock, is there any info other than what i have tried?
1500esp-1999 toyota sienna
tried to use trunk release as an additional pulse to open passenger doors,and tried to open the "motor wire" on the drive side kick with a relay to prevent tne other doors from unlocking untill hit with the 2nd channel output. any info other than what i have discribed would be a great help.

It's pretty easy on Toyotas, but you must first do a test to verify something.
Lock the doors and close them; stand outside the car with the key in your hand.
Insert the key in the driver's door, and very very slowly, turn it to the unlock position. Carefully watch the driver's door lock paddle switch.
As you turn the key slowly, the driver's door should at some point jump open, electrically. A second twist of the key will unlock the other doors.
(If the driver's door only opens mechanically, the car does not have two-step unlocking.)
Anyway, just go to the driver's kick and find the wire that tests off the driver's door key cylinder. I always forget the exact color...try for blue/white, blue / YELLOW.........well, I think it's blue anyway.
Once you find the wire, it's simple from here. One pulse opens the driver's door, and a second pulse within five seconds opens the others.
