Hmmm....like idea of the control for exhaust brake...maybe have see hot it works...my exhaust brake at THIS point is non functioning...n Not in rush to mess with it.......yet
Depending on how fancy you want to get, it should be really straight forward. I'll probably hardwire the button on the shifter and just use the automation for things like start up procedure. Maybe set it up like some of the other trucks do to close during warmup to warm up faster.
