Swapped my wonky '85 cluster for one from an '87, and the oil light flashes
and the buzzer buzzes all the time.  I have an OP gauge, so I know
everything is fine.  I need to rework the later type OP warning system to
work in an '85.

There must be a way to jump the plug or something that goes into the speedo
to make this work, anyone know how?  I've unplugged it for now. Even with a
gauge, I'd like to have the light, and now it doesn't come on when the
ignition is switched on.

The GoWesty foil replacement kit says it has a dip switch for this, so it
must be possible.

Thanks!

Stuart
