does a 1994 you 280 have the 9 pin connector for engine diagnostics
No, you should have a mechanical engine, not the electronic controlled engine
Ok
So no connection for the vm spec folks talk about.
It has ab audit system. Does that provide engine monitoring
There is also another type connector on my 1993 U300 with 6V92
It is a straight 9 pin, Told by Silverlight that it was an Allison proprietary connector and they could not mate up to it.
Jim Shepherd (303.478.3501 ) matched it up and had it installed on the JIB.
Now have VMSpc with most PID's
THANKS BILL!
All this discussion made me curious, so I looked under the dash. I found a connector with a cap on it that said "Diagnostic Connector." I pulled the cap off, and found a flat arrangement, two horizontal rows of six each. In the glove box was an adapter that has 12 flat pins (two rows of six) on one end and what looks like a serial port on the other end. Slots on the adapter seem to match up with the diagnostic connector, except that it looks like the diagnostic connector wants round pins and this adapter has flat pins.
Pin arrangement is:
x o o x o o
o o o o x o
where x is not used.
If I get the Silverlight software and a suitable netbook, will I, too, be able to learn all sorts of wonderful information about my engine?
Silverleaf has a document on connectors along with other useful documents: Manuals | SilverLeaf Electronics, Inc. (http://www.silverleafelectronics.com/?q=node/10)
In particular is one on connectors "J1708-J1939 Diagnostic Connectors.pdf"
I am sure someone will chime in but I am reasonably sure you cannot use them on the "mechanical " engines only computorized.

Okay so the engine temps won't be on that 9 pin either
John, the connector you see is for the Allison Transmission,
