Harley Davidson Tachometer-2003 Road King + 2005 tach with 7 wires. @ I had a tach with 3 wires working ...but want to replace with this one because the face matches my speedo, better. I have found the combination that allows the backlights to work....but, not able to get the signal wire from bike pink to connect to the correct one on the tach?

SOURCE: 1998 harley davidson cuts out when bike gets warm

Check the ignition, pull the points cover off and then put a heat gun on the ignition and heat it up to see if the bike will cut out. I know you replaced the coil if you can check it again to see if you have 12 volts coming and in and out of the coil after you get it to fail just to double check thats the problem.

According to most posts the pink wire directly connected to ECM would be the TACH relay to AutoMeter Tach Gauge. 2001 FLHR can anyone reassure me on this one? Thanks inadvance

http://www.officialharleyparts.com/harley/2001_all_flhr_i_ci_dom__and_int__models__ignition_circuit_sheet_1_of_2.jpg

Kind of hard to see in the above wiring diagram, but the OPTIONAL tach is a PINK wire that goes to an 8 pin connector.
Pin #3 is where it connects.

From there is goes to the ignition harness, if a carb model.
-OR- to the ECM harness if a FI model.
