I found someone to install my VIPER 791XV alarm. I need the wiring diagram. Anyone know where I can get it.

Hey man I just cut and paste, I have no idea what the asterisks are for.

Notes:
*1 When doing remote start, this wire must be isolated from the keyswitch with the ignition relay. *2 The BCM is located just to the right side of the radio. Remove the radio to access. *3 To avoid dome light delay, use red/yellow at the driver door pin for the driver door and red at the passenger door pin for the passenger door. Isolate each door trigger with diodes. Also available @ BCM *4 There are 2 blue/red wires in the ignition harness. The correct ignition wire is the heavier gauge one and it has 1 silver hash mark. The incorrect wire has 2 silver hash marks.
In reference to Note 1.. see this: http://www.directechs.com/techtips/pdfs/resources/security/directed_techtips/1077.pdf

From my notes on the 777:

777 to Celica
  • Red +12V = BLK/RED/WHT ignition - under steering column
  • White Parking Light Out = Lt. GRN steering column
  • Brown = Siren's red wire
  • Brown/White Horn Output = Lt. BLUE/BLK under steering column?
  • Black/White DOME = wired to optional relay that applied GND to RED/WHITE DOME wire in Driver's kickpanel that goes up A pillar... I seem to recall there are two.. and it is the one closer to the firewall?
  • Blue Trunk/Hood = Lt. GRN 'B' connector, pin 22 on Body ECU
  • Yellow IGN = BLK/ORANGE under steering column
  • Black GND = GND
  • Green NEG Door trigger = diode isolated to the door switch inputs into the body ECU... I'd have to look up the pins & colors.
  • GREEN Neg Door Lock = Master Lock switch (center console) input to Body ECU
  • BLUE Neg Door Unlock = Master Unlock switch (center console) input to Body ECU
I did the door locks thru the Master.. it was just easier. Only disadvantage is that the passenger unlocks, too... vs. only the driver's. Wasn't a big deal to me.

Orange Armed Output = Starter kill relay wired off the BLK/WHT starter wire (under steering column) so that it was normally closed.. & took it's POS from the BLK/WHT... orange went to the other coil pin on the relay. You'd have to have a decent grasp of starter/ignition kill relays to understand.

I used Gray AUX 1 wired to the headlight relay... so that headlights can come on remotely for 10secs.

Glass break sensor went inside the OBD II connector port. Shock sensor went to dash crossbeam. Microwave sensor went in center console aimed @ sun/moonroof.

I didn't do a remote start on it. You could do it... but, you'd have to install it on the starter side of a starter kill (momentary relay off the latched AUX1).... bypass the clutch switch... and provide an ignition on source (latched AUX1).... & probably disarm the alarm (option 10 for AUX1)... and be very very careful never to leave it in gear.

But, you would probably be much better off with a unit made with remote start features... & protections..... such as ensuring neutral, rpm sensor, parking brake sensor, etc.

or get Scytek's Add on Remote Engine Starter System
Use the yellow/black |- |passenger kick or BCM *2 for the two pulse unlock.... 1st pulse driver's, 2nd pulse passenger

I'll add this, too:

It's not exactly a simple plug & play. You will need to understand relays, possibly diodes, basic 12V wiring techniques, etc. www.the12volt.com has a wealth of basic info. If you have a problem understanding a particular part of the install, then I can be of more help.

The electrical info for the Celica can be found here: http://www.newcelica.org/forums/showthread.php?t=4336

It would be best to sit down and map out how you are going to proceed (i.e. what wires go where, what options you will use, & what programming you need to do) before the day you do the install.

A 2005 has this same wiring diagram right?

For alarm wiring? I'm fairly sure it does.
