Most if not all cars have a keysense wire. The only difference may be the fact that the bypass module needs to use the keysense wire for programming for some toyotas.
As far as the lock wires go, did you test the wires to see if they were to correct wires. Or if those were really your arm/disarm wires, the disarm on most toyotas need a double pulse unlock. That can be changed in programing the alarm.
The12volt says that LOCK is Blue/White (not purple) and UNLOCK is Green/Black (double pulse) both are negative found at the drivers kick.
Another one says the same colors as you posted.
I cannot verify if these wires are correct since I only have directechs access from work and I don't have your car in front of me. So always verify with a meter before connecting.
RTFM! Its all in the manual. The data wires needed for the bypass are located @ the key cylinder. The link for the manual tells what location they can be found. Since your car is type G, then look at page 3, it illustrates a 7 pin plug and the data wires are in pin 4 and 5.
That data link is intended to link to the alarm. Since no other features are utilized, you can choose either method. Just dont forget to hook up your status/ground when running.
