My ECM is located in the elec compartment on the left side where the elec cord reel is located.
If you could describe what problem(s) you are having we could be of more help.

Are your gauges the Ametek NGI series of instruments? If yes, i have some prints.
Did you find the ECM?

One thing to try with the Ametek NGI system is to check the main connection on the back of the speedo. The speedo has the processor that sends the signals to the other gauges.
On the back of the speedo are two main connectors that are, I believe, labeled SC1 and SC2. (Dont have the prints in front of me). There should be one wire bundle connector plugged into SC1 and SC2 should be empty. Remove the wire bundle connector from SC1, check for pins that are pushed back or loose and not making contact, then connect it to SC2. Doing this helped me with a temporary lose of signal to various gauges.
Once you gain access to the rear of the instrument panel you will see that all instruments are daisy chained, with the speedo being the main bus driver that receives its signals from the ecm.
