I have searched but either can't seem to word it correctly to find what I'm after.

I'm looking for circuits that can allow me to control vehicle systems with single momentary NO switches but to cycle through 2 or 3 outputs.

For example

Initial state = all off
First press = relay 1 on - relay 2 off
second press = relay 1 off - relay 2 on
3rd press = relay 1 on - relay 2 off
4th press = back to initial state

These will be used to control wipers, lights, heater fans etc in a modified classic mini so ideally need to be simple, robust and able to work on variable 11 - 14v supply. I'm able to solder and have put together very basic circuits in the past using strip board PCB but have basic knowledge of circuit design.

I hope that explains it.
