Yamaha/HDS Digital Trim Readout

[daxt79]

I recently installed a nmea 2000 system to my Yamaha outboard. I view the gauge readouts on a Lowrance HDS unit. Everything seems to be working fine except for the digital trim.

I've connected the two pink wires under the engine cover, but can only get the display to read 124% trim no matter what my motor height is. I've also made some adjustments to the mechanical pivot arm mounted in front of the engine with no luck.

Does anyone have any input as to why the trim will only read 124% on the display? What am I doing wrong?
