6 volt car Intermittent Windscreen Wiper

AS1093KT - Intermittent Windscreen Wiper Controller
I would like to use this wiper controller for my 6 volt vintage car. Can you help with the components to be modified, and do you offer those?

This has not been tested but the circuit will most likely work fine when you replace the 12V relays with identical but 6V types.
Your distributor can supply these.
