Oil pressure switch/ light

Hi,

I have a 20vt running megasquirt, I'm having my oil pressure light flashing. Does anybody know what I have to do with the 20vt pressure switch, because I know the mk1 original engine uses 2 switches?

Cheers

use the old pressure switches and wiring, bin the mk4 pressure switch and remove the allen blank from the other hole job done

Cheers John!!
