Actually my plans require the ECM to get the fuel. My truck is a '92, and the factory gauge won't work with the '98 fuel sender. (I ran a '98 tank to get a fitting for the vapor pressure sensor and a 40-250 ohm sender.) I plan on running three android tablets as flat panel displays in the truck. One for the gauges, one for Navigation & Data, one for music. the last two will be interchangeable as far as functionality. Gauges will be run off the ALDL port, so fuel level to the ECM is important. If that doesn't work I'll have to change my plans dramatically.
