Wiring in old cars tends to build up resistance over time, and the switch for devices takes the full load of the circuit. A relay allows you take the load off the wiper switch & wiring by powering the wiper motor direct from the battery or another good power source. Commodores from VK onward used relays for most high load devices such as wipers, headlights etc in order to reduce the chances of voltage drop and resistance build up in switches.
ahh okay.. thanks.. ill look into it i can get standard relays from work...
i pulled off the wiper arm and it has fine teeth where it will grip on so hopefully the
VL ones will fit strait on!
