Hydraulic Trim Tabs 2016 Grady 330

[Beast of Burden]

I believe I have a malfunctioning sensor on my port side trim tab. Both tabs go up and down (fluid level perfect) but the led indicator doesn't track the up and down correctly on the port tab indicator. I spoke with a Bennett tech and performed the calibration exercise several times but the situation is unchanged. The tech said althou it is likely the sensor on the tab he would also check the module by switching the port/stbd leads at the module and seeing if the problem switches sides on the indicator . The wires from the tabs pump suggest the module is under the electric box which I am not anxious to remove. Does anyone with a 330 know for sure where the control module is? Also does anyone know if the round access hatches just forward of the engines will provide access to the inside tops of the tabs and if the hydraulic and electric leads need to be detached from inside to pull out the top part of the tab? Thanks!

Did you get an owners manual with the boat. There should be a wiring diagram and location in that book. If not, I think you can download one from Grady's site

I have the wiring diagram for the tabs but it is not overlaid on an actual boat the way many of the systems are
