Does anyone know if there is a gateway to connect a MEFI 4 to a NEMA 2000? I have the Garmin 740s. Running out of dash space for gauges.

what guages are you adding? maybe this would help. Its what I used. http://www.nolandeng.com/rs11.php

I called them they said at this time they do not have anything. I want to connect my Garmin 740s. Witch can be wired in by Nemea 2000 or 0183.

But what guages are you wanting to add? Because although they dont do the conversion you want they can take the signal from your motor and convert it to nema2000.

I used the above device and did tach, oil temp, oil pressure, water temp hmmm forget what else.

Just thought although its not mefi 4 to nema it still may be of use to you.
