[GreenKeys] AN/UGC-74 service manual or pinouts

[Kirill Levchenko]

Hi list,

I have an AN/UGC-74A(V)3 and I'm looking for a service manual or a  
pinout for the data and power connectors. I found an operator manual  
online, but it was little help with respect to the above. Also, during  
transport, a viscous grey oil spread on parts of the the circuit  
board, mechanical parts and rubber rollers. Any tips on the best way  
to clean it off?

Thanks,
Kirill
