after much fiddling to find the issue with my wipers & horn (sorted now) i noticed a metal cased relay which is in place, according to jeff bowlsby diagram, for the headlamps. I would like a plastic cased one to stop any interference.
The relay is
803941589 vw.
2x150 watts
with pins 56, 56a, 56b & 30
Is there a replacement for this? All i can see is relays with pins labelled in the 80's and rated in 30 or 40 amps only with no mention of wattage.
