ECU MAXX displays have a metal connector shell and two release pins, one on each side of the connector. It also has labeling that indicates ECU MAXX on the back of the display. If the display has these characteristics, this is the correct replacement display.
Most ECU problems are not related to the display. Button problems and burned out LED’s are really the only problems with these displays and they are rare. Control boards are not available so please see our FX-2 conversion guide for replacing these systems.
This display has the identical appearance as the FX-Maxx series of control displays. However, it uses a different display interface cable and is functionally incompatible.
