[W126 Coupe] 1- doesn't start in cold 2 - oil pressure strange

[Shayegan, Richard]

Mine will stay up at three sometimes, but I don't think it's because of
a gauge fault. I don't know how to solve your problem, but speaking of
gauges, what does your oil pressure do when you have the ignition, not
the engine, but just the ignition on? Mine goes up a tiny bit from 0,
and if I watch it closely for a little while I'll notice it twitches
slightly periodically.

Mine is a 84 500SEC EURO
      My oil pressure gauge has been reading full on 3 for some time .
As
soon as i start up , it shoots up to three and stays there !!!
  Replaced the sender unit yesterday ,but, the electrial connecting plug
had
a problem.  Opened the cover and discovered 2 loose wires, one short bit
on
the oil plunger and the other going to the dash but not connected to
each
other.  Can this be repaired ? if not is there a part number for this
connector. And ,or, does it have a name?
 Tried joining the 2 wires. Result-  oil pressure goes to three and
stayes
there.
P.S.
   I change the oil and filter every 3,000 miles.
