Nipper, yes the 2006 is a drive by wire. My best option for my application would be to adapt a throttle body with mechanical linkage and a position indicator (which the new ecu needs) to the 2006 manifold, that would require the least amount of modification to my existing setup. Remember this is on a boat and the controls (shift and accelerator) are on hand controls. It is possible to install the accelerator but the wiring involved between the engine and foot pedal would cause some problems.
