Since you’re controlling with a Raven, your options are limited. I sold an Outback Automate to a guy on AgTalk last year. It connects into your Raven and controls the sections. You need to come up with a cable to provide GPS signal to it from your receiver. The AutoMate was made by Raven actually and they had the same thing branded Raven. That would be your least expensive option if you can find one. It worked ok, a bit awkward to set up, but not horribly bad.

I don’t know what kind of controller you would need to be able to run it with your Trimble display.
