Suzuki twin helm trim

[choc_e]

I have twin Suzuki df140’s on my KC. When the trim switch is in the “both” position the motors trim up together. However, when I go to trim them down they trim independently.

It’s not the end of the world and I have lived with it for some time.

Does anyone have a solution or a schematic/wiring diagram for how the trim switch is wired? (the one or two motor selector switch) I haven’t even attempted to fix it yet, but keep thinking about it (at work) and thought I would ask.
