Can anyone tell me where I might find a schematic or wiring instructions for the three pin oil pressure sending unit that is installed in my 912 ULS? I am having problems getting it to work with the Aviasport gauge that I am using. What I need to know is which pin does what in the sending unit. It is a BPR 456180 43/12 type PAA-21Y/81649.99 if that is of any help.

I'm not sure what the BPR sender is, but you most likely only need two wires. Most of us use either a single or double pole VDO sender or the newer three wire, but only using two wires for the new electronic sender.(Most here are familiar with the Honeywell unit by name)
