As each paddle is pulled, it brings another resistor into play to give a high signal or low signal. Not so simple. Less plug and play, more plug and no play.

The push/pull ones are from an LCi car.
My car is a late LCi with the pull/pull blades.

Looks like I'm going to have to live with it for a while, until I get my thinking head on and delve into the circuitry inside the switches.

there are threads on the us sites for the wiring and resistors needed
