Anyone have a wiring diagram f

Anyone have a wiring diagram for trim sender and instrument for a Mercruiser 5.0 EFI 2001? Measuring on the instrument while tilting the drive shows an increasing/decreasing voltage on the instrument but the needle is steady at full as if the drive was all the way up. My vote is that the instrument is broken but how to be sure?
 
"The voltage on the instrument

"The voltage on the instrument is changing when tilting the drive. Thus the gauge is working, sending info to the instrument. Further investigation showed that there are 2 coils in the instrument and one is broken. Still interrested in a wiring diagram though."
