02 Sequoia Remote start with oem remote

I just bought this Vehicle and wanted to add remote start to it using the factory remote.  Has anyone done this?  It seems that the Factory keyless is built in with the BCM.. any help is good.. I've seen post on this subject before but its been awhile.. pls let me know what you did and modules  you used..

thanks

na.....that should be all you need for wiring info.......directwire is the probably the best out there.

are you talking about the channels on the factory transmitters and where the wires are? I don't. If you use the system i listed for you, you dont need any of that stuff. With the add on systems, u tap into the motor wires of the door lock system......generally when the system is done, to start the car, u press....lock, unlock,lock on the factory transmitter or lock lock lock.....this combo tells the remote start to crank.......

I have a few dealers that like the single button RS units on Toyotas. It does suck that you need to use a key to get in, but they also are cheap and don't want to get into a keyless/RS unit if they don't have to. I think using a RS on the factory remotes is worse tho, you can't even turn the RS off unless you let it time out or get in it.
