Hi Sean, the power is included with the LMF-400/EP-10 package. The extension is also included. You will need 2 EP-15 fuel level sensors and the speed sensor only. To convert to the red LCX-28 we can send you an adapter connector. LCX-28's should be available at some point this month (how's that for vague

) We keep an eye on supply to make sure out customers get units as soon as they are available.
