USA Urq Oil Pressure Monitor

[ejfluhr@austin.ibm.com (Fluhr)]

Just an FYI, for those of you with an early urq (old style fuse box)
that have added the Coupe/4K style oil pressure sender, you can install
a Coupe GT oil pressure control unit in the proper relay socket to
enable this system.  That system ensures that oil pressure is above
1.8bar when the rpms are over 2000 (i.e. a safety check).

The trick to this is the fact that (1) the stock wiring harness contains
all the necessary wiring, (2) you replace the oil low-pressure switch
with the gauge sender and its associated high-pressure switch, (3) you
connect the old low-pressure switch wire to the new high-pressure switch
terminal, and (4) you remove the jumper in the relay socket used to pass
the low-pressure switch connection to the dash light.

I do not know if this will work on the later style urq with the underhood
fusebox, although I do not see why it wouldn't (I was working from
the Bentley 1984 tqc wiring diagram).

This works nicely on my '82 urq.  Basically it replaces the loss of
the low-pressure safety check when you install the oil pressure gauge
(unless you keep the low-pressure switch somehow).  Also, you get
the annoying buzzer when the warning light goes off.

Apologies for the bandwidth if this mod is already well-known in the
urq community.
