Found a product that might be of interest to some of you that like to experiment with your experimental, especially if it saves you a few $$.
It's a 10 amp forward and reverse relay module. Should run off the GAD 27 or GSA 28 outputs just fine to power the trim motor.

Ordered one today. I'll report back when I do some testing.
