It depends on your car's electric bus design.

For example your car may have a seperate ignition & FI bus powering those devices and another for accessories and the instruments. If they are seperate and you tap the turbo timer into the ignition & FI bus then those items on the seperate bus will not be powered.

If all the systems are on one bus then all that stuff will stay on till the turbo timer shuts down that circuit.

Just try hotwiring the appropriate circuits and seeing what happens. That way you will know what circuits or circuit you need to tap into with the turbo timer.

Be careful when doing so. You might want to use something with an in line fuse so if you get any paths crossed you won't have to worry about smoking any of the paths in your electrical system.
