i need a diagram for install this alarm.
in my city nobody knows celica and don't install the alarm...

Do you mean the car wiring diagram?

If so here it is:

Door Lock Purple/White (-) Switch in Center Console
Door Unlock Pink/Black (-)

Windows Down LF=Red, RF=White/Blue

i thought you had to wire the alarm strait to the ecu. am I right?

???????

NO! Where did you hear that? Only thing you go to the ECU for is the tach wire for a remote start install...

thanx man thats good to know

I know this is a really old thread, but I was hoping to get some help with wiring an AVITAL 3100L alarm into a 2004 Toyota Celica. I can't seen to match up the diagram you posted above with the alarm wires.

I bought a VIPER engine imrmobilizer alarm system to replace the original unit in 2002 Celica GTS.

The guy said they are all connector compatible. He removed the old one and plugged in the new unit. Works great. No problem.
