i'm pritty sure a mk3 one is ok - ive fitted a mk3 switch onto a mk2 loom and i only needed to do 1 mod - linking a wire somewhere, cant rememebr what it was for

but i got no fuse blowing problems
i'd need to look at a drawing but i think there is a relay unique to the intermittent - i'd look at that 1st
i'll see if ive got any drawings
