2026 Tohatsu msf40a wiring

[jackforey]

Hey so I picked up a new tohatsu and the shop neglegleted to order the control box they did have a harness and side rigging harness but I dont have the ability on my boat to side mount a controller (it's previously used boxes) without building a large enclosure for it. I ordered one on Amazon and it only has the 1 8pin and 2 little wires where as the rigging harness they had used both the 8 pin and a 3 pin I already determined that 2 are for trim (worked but motor wouldn't start still) what's the 3rd wire does anyone have the diagram I might be able to make this work? Also anyone with 2023 or newer tohatsu please send picks of the control box and how it wires in. Or if you can help with the newer diagram I can trace what's new. Needless to say Monday I'll probably have to order the box from them and wait a week, was hoping amazon could save me 300+$ they sell them for 650 at the shop and 300 on Amazon seemed nice.

Year is irrelevant. Model is critical.
