Re: yamaha remote control with trim/tilt
depending on the box, it simply wont matter.
the 703 7 pin box did not have trim the 703 box 10 pin did.
use the 10 pin control box harness on a 7 pin engine and you wont notice anything as the extra 3 pins would control trim switch power and trim up and down.
dont make it hard

but we still dont know what box you have and they make like 7 or so.
