Lotus Excel fuel sender replacement with centroid dip type sender(1)

Looking around the trunk area while Replacing my lotus excel's fuel sender with a dip type fuel sender. The vdo sender was bad and needed to be replaced. This centroid product was custom programmed at the factory to my specs and had smoothing tech in it to reduce sloshing fuel gauge wobble. The low fuel alarm wasn't a one wire hookup, but easily managed with a relay due to the odd lotus low fuel warning light system. The system also needed a +12v which was taken from the flow lock valve which is ignition switched.
