Don't do it that way or you will have NO oil pressure warning light at
all. Yes, unplugging the board as Chris suggest will stop the buzzing
but it is important to have a working oil warning light.

There is an easy way to keep the oil warning system working and make it
compatible with the 1.9 wiring. On the back of the speedo is a small
connector that plugs into the oil warning circuit board that lives
inside the speedo case. Unplug it temporarily and bend the outside end
pin of the the group of 4 pins over to the side. Then plug the connector
back in place while making sure it misses the bent aside pin.
