The Fleece controller I had only connected to an unused 3-conductor data plug near the APPS. The only two parameters the unit utilizes is throttle position and RPM, doesn't monitor boost pressure.
The early model controllers had a MAP sensor plug, but it should also have a plug that is matching the MAP sensor itself. Plug the turbo controller into the MAP sensor, then plug the power module into the wiring harness on the turbo controller.
