Making a wireless car steering wheel buttons system for switch 16amp rely

[whensparksfly]

I need help with making a wireless steering wheel buttons system for switch 16amp relays. I want to have push buttons on the steering wheel to work the wipers, indicators and maybe the fan but it will need a larger rely im a total beginner.
I was thinking of using a pcb rely board and rf transmitter but can find or if I do find anything I don't know if it will work.
thanks for any help and happy new year

If you have buttons on the steering wheel to activate a radio transmitter then it will need to be powered from a battery that will frequently need replacement.
The relay might need a transistor to drive it and a radio receiver must be used activate the transistor.

have you any links where to buy the parts

The radio controls for my model airplanes are much more complicated than simply turning car things on and off so I buy them already installed in the airplanes.
I do not know any place to buy the parts that do what you want in a car since cars already have them.

As the inside of cars get very hot and very cold, frequency stability of a RF system could be a problem, I would use infra red.
