Beside not paying attention to the gauge if the oil pressure goes too low -
can't see a problem.

Personally I would disconnect only half of the factory oil pressure system.
There is a 1.8 BAR and a 0.3 BAR sender - leave the 0.3 BAR active and
remove the 1.8 BAR and put your gauge sender there.  I think all you have to
do is ground the 1.8 BAR lead and you won't have any problems.  The senders
that I have seen from VDO screw into a standard sender hole and have two
terminals on it.  A 0.3 BAR and the variable one.... go with one of these.

Subject: Arguments against using VDO oil gauges only?

Hi folks,
    Does anyone have an argument against disconnecting the "dynamic oil
pressure sensor" with all its lights and buzzers, and using a single sender
VDO gauge instead? I have not trusted the original system on my 88 GL since
I got it, now with a new speedo, tons of spliced wires in the engine bay,
and at least one bad pressure sender.  I think I'd rather just interpret
actual numbers, than to be unsure whether I've got bad wires, bad senders,
or bad oil pressure.
    If I end up pursuing this course, does anyone know where to get a single
VDO gauge sender- doesn't seem like the list vendors are carrying them.
thanks for any input
