If my memory serves me correctly--one oil press switch is a normally open
type and the other is a normally closed style when no pressure is
sensed...If a "grey"switch is put between the pushrod tubes...the system
still will not work...It has been a while and I don't 'bemember which is
which but the grey switch is not the one between the pushrod tubes and is
a .9 Bar swx...the otehr is a 1.4 or 1.6 bar swx I believe. Good luck
