BTW, these Turbo Timers. If you remove your key and leave the vehicle could someone still drive away while the timer is active?
not if done properly. key word being properly. any system designed to have the engine running while the vehicle is un-occupied would normally be equipped with a fail-safe of sorts, the usual one is to shut-off the engine if the brake is applied and no key has been put in the ignition, being that you need to apply the brake to shift out of park, you can't go anywhere without the key. (that's how mine works anyway)
I didn't wire in the remote myself, however the basics are that the Delica only has power locks on 2 doors (passenger and sliding) the driver's door is just the switch that controls the other locks (it remains manual) to make a full power system you put a solenoid on the driver's door lock, and then power that from the remote (running new wires to it) making the existing wiring irrelevant.
To control the tailgate from a remote you simply tap in to the wires on the back of the dash switch.
Wires for the starter can be found inside the steering column (back of the ignition lock) and a brake input can be taken from the brake switch (on the brake pedal)
