Wiring on old GRT EIS unit

[egp8111 7]

Anyone happen to have any manuals or knowledge on wiring the old two D plug style connectors on a GRT EIS unit ?  The newer units had one bigger D connector but this one has two smaller one.  I've been able to match up one to the engine inputs (egt,oil ps,cht i etc).  The second connector just has three wires so I'm assuming one is power, one is ground and the third goes to the warning light but they are not marked and I don't want to hook them up wrong and let the magjc smoke out.    The folks at GRT are looking but so far havent been able to find anything!    

 

Thanks,

EG
