about mid way down this page is as far as i have seen someone get into deciphering one for use, about as far as i would go using electricity to run it if no one came out with a reasonably priced universal controller would be a linear actuator, but i think i can get all i want out of it with mechanical means, a working E brake, rapid spool and cool top end, if i can get this thing working well ill jump on a #10 plate and a south bend clutch, the only thing i see with the current plan being a issue is if i can't find a vacuum actuator that will do what i want, which is put it into the E brake function and pull it back out when vacuum is released by spring, if it can't ill be adding a air compressor to the truck and use that to oppose the wastegate on the other side of the seesaw type linkage i plan to attach to the vg rack

Basically you'd need to figure out the voltage range needed to control the vanes, plot out how far open they should be vs. boost pressure, come up with a good pressure sensor that you can use to generate a signal in proportion to boost, then have some sort of amplifier to drive the vanes controlled by that signal.
