Does anybody know exactly what type of signel the speedo is looking for on the databus? How about the Tach? I need to get an ECM to run some gauges (aluminum faced off an 04 FLHT I think). Since this is all I need the ECM for could I use any o4+ ECM to drive the gauges using pickup sensors into the ECM? I have a SPeedo Healer for the correct pulses in... just trying to figure out what data or frequency these things are looking for and what ECM I can get away with driving them. I have the blinker module already which shows to be part of the circuit. I am outfitting my bike with teh 04 Batwing with gauges. This is the last thing I ned to get working.

Thanks for any help,
