Subject:      New Dash Pod/Dynamic Oil Pressure
Content-Type: text/plain; format=flowed

I recently installed the new dash pod with tachometer (purchased from Bus
Depot)into my 84GL. The re-wiring instructions recently posted by David
Beierl worked great! Thanks Dave!

I ran a few extra wires from the dash to the engine compartment to be used
later for a VDO O.P. gauge and a high pressure oil sender. In the engine
compartment I grounded the H.P. oil sender wire (from new dash connector:
pin 12) for the time being to prevent the buzzer and LED from "going off" at
higher RPMs. I re-installed the original speedo from my '84 into the new
dash pod. The electronics in the new speedo (part the dynamic oil pressure
system) doesn't actually sense speed or otherwise depend on the speedometer
mechanics. The electronics PCB in the new speedo can easily be removed and
mounted on the back of the old speedo. I made a cardboard sheild and covered
it with duct tape to protect the PCB from getting dirty or shorting to
anything. There is a small "open" relay on the board that needs to be
protected from contamination and mechanical contact. As far as I can see the
additional electronics is simply mounted in the new speedo because of space
limitations in the tach.

In order to take advantage of the dynamic oil pressure system, I plan to
purchase and "tee" the (second) high pressure sender, used on the 2.1
engine, with the standard low pressure sender located between the pushrod
tubes. I have to source a SS hose (or extension) with a "tee" connection to
do this because of the limited space between the pushrod tubes.
