703 controls

[BQUICK]

I've got two 703 controls here. Neither one has power trim but one has a 7 pin connector and the other a 10 pin cable.
The brand new one in the box has 10 pin but shouldn't it be 7 since no power trim?

all the main harness these days are 10 pin, with or with out power trim,
