Sorry guys a bit of a stupid question:

I can't for the life of me remember how I did this and I can't get it right, probably a case of dumb A$$ syndrome
I have a level sensor in my sump I want to measure when the water is to low but can't for the life of me remember which one it was!
Also in the P4 does it still support the old keyboard type level sensor connector?

It is a GHL level sensor.
