[Public-list] Universal 5411

[Bill Blevins]

John (or anyone else),

Another 5411 question... I have a new Universal Admiral instrument panel 
and I have a wire that is supposed to go from the ignition on the key 
switch to the oil pressure switch. I located the oil pressure sender and 
another wire goes there, but have no idea where to look for the switch. 
On my schematic, they appear to be two different things.
