Anyone have the correct info for '07 Corolla? Check a few sources and am getting mixed info for lock/unlock as well as some others.

Just did one of those this morning.
Driver's kick panel, you can plainly see the wires that come in from the driver's door, and they run to two plugs.
In the top-right corner of one of those plugs, get the green wire, and the blue / YELLOW wire.
These wires will test as a ground when you turn the key in the exterior lock cylinder of the driver's door.
(I think the green is lock, and the blue / YELLOW is unlock, but it might be the other way around.)
The unlock wire is a two-step setup. That is, if you give the wire one pulse, it'll unlock only the driver's door. Pulse it a second time, and the other three doors will unlock.
If you want ALL the doors to unlock every time you press "unlock" on your aftermarket remote, program your unit for double-pulse unlock.
Also, the domelight will come on when the doors are unlocked, as long as the remote starter isn't running.

I prefer using blue/white as lock and blue / YELLOW unlock two pulse. Seems everytime we use the green we have an issue with it not working after the car sits. Also, the car actually is only two step unlock if it has factory keyless to begin with. If it doesn't have keyless the first pulse does nothing and the second unlocks all. The drivers door will not unlock on the first pulse if there's no factory keyless....
