Some more info on this:

Memory triggered by Ken Lewis' response,  I went digging around on my
hard drive for some info I had clipped from archive searches and emails
I got last fall when I asked about this.

The 86+ clusters have high rpm and low rpm oil pressure alarms and
sensor.  The 85 and below engines, 1.9l, do not have hi and low rpm
senders, only low.  [This may only be approximately correct
technically.]  I think the high rpm oil pressure sensor on the 87 panel
is looking for something  from the high rpm sender and getting nothing
and hence sounding off.  [Apologies to Mark Drillock if I am butchering
what you posted.]

I thought from what I read that I could just wire this up to the green
wire and be OK, just that I was not getting any high rpm pressure alarm
capacity.  But that must be wrong, or maybe I put the connection between
the wire from the coil and the cluster wiring in too early.  I hooked it
into a 4 wire connector right behind the fuse panel that has the green
wire from the tach that is before the green wire in the 14 wire
connector.  Would the place in the tach wire trail where I put in the
"juice" impact this problem?

So, I guess the question is how to ground the circuit and shut the thing
up.  Or change the location of the signal from the coil and bypass that
oil pressure circuit?

Thanks again.
