<VV> Oil Pressure Switch

[Bob Gilbert]

Hi,

 

Does anybody know the thread size of the standard oil pressure switch? I
have a manual(non-electric) oil pressure gauge I want to plumb in to check
the actual oil pressure.

 

Also, I have what appears to be a regular oil temperature switch but with
two terminals sticking out of it instead of the usual one. Does anybody know
what that might have been used for?

 

Regards,

Bob
