Hey All,

Thanks to mark Drillock for clarifying a few things for me on this
situation. We were able to get this figured out and we have successfully
disabled the Buzzer.

The key is this (and forgive me I don't have the Bently with me to give page
nymbers exactly - I think Mark referenced page 90.23):

'86 and up Gauge
There are a total of 6 pins on the back of the speedo housing. They are
grouped as a set of four and then a set of two (from left to right looking
towards the front of the bus). In the bently they are numbered from 6 - 1
left to right.

6. Terminal 1
5. Ground
4. Oil Warning Light
3. +

2. 0.3bar oil sensor
1. 0.9bar

 If you want to install this '86 and up gauge into an '85 or older you have
to carefully bend pin #6 out of the way so it no longer makes connection.
This will take care of the problem.

Thanks again for everyone's help with this.
