I am looking for the wiring diagram for a 2003 Honda Civic to install a remote start and cannot find it anywhere.  If anyone can help, I would greatly appreciate it.

Notes:
NOTE: This vehicle has an immobilizer system that needs to be bypassed when adding remote start. Use DEI part number 555I or 555U. *1 The factory alarm plug is a green plug above the drivers kick panel. *2 The drivers door trigger is green, front passenger door trigger is lt. GREEN/ red, and the rear door trigger is GREEN / WHITE. *3 In the top left plug. *4 It is a 2 pin plug to the passenger side of the battery. *5 The PCM is behind the glove box. The vss is in a connector A (31 pins), pin 18. The vss is also blue/white at the cruise control module to the left of the steering column.
