It looks like the nb Miata setup can be used. Integrated controller and pump. Wiring diagrams are at the bottom of the page. It has separate front and rear fluid paths so it can be used with a bias bar but is only 3 channels and no software support so it is mostly for keeping from flat spotting.
They are only a couple hundred bucks on eBay. I have bee thinking of getting one and see if I can get it to read c5 speed sensors.
