Tachometer

hello everyone
i have a harley fxdwg 2004,1450 cc
i bought a tachometer, there are 3 wires,1 yellow,1 red,1 black
the red and the black are connected ok
but the yellow one should be connected on the pink wire tucked inside the conduit at the speedometer connector but the probleme
is there is no pink wire there on my bike
would anyone know where i could connect this wire
in order for my tach to work?
i tryed on one of the coils but it s not working
the tach comes from harley davidson
thanks

If you have a service manual for your bike, I would definitely look there first. That would be my only suggestion. Sorry.

I'd never cut into someones wiring without first looking at the wiring diagram and I do this for a living. The most important tool you'll ever buy is the service manual.

vybs right but if'n ya bought it from the stealer it should come with instructions if ya bought it on say ebay then ya might have to call the dealer ooorrrr, look it up in that handy little manuel eh.

I found some directions for installation of a mini tach on a 2003 or newer dyna and found that there is not a tach output wire in the harness. The newer bikes communicate between the ignition module or ECM on J1850 wire which is ltgreen and violet and then converts the information inside the instrument. The good news is that pin 3 on the speedo is not used but it has the signal that you need to hook up the yellow wire from your tach. You would need to put a pin into this connector. If the tach that you are trying to hook up is a Harley part number, you could get a copy of the instructions from your dealer. All the service department has to do is go on line and print out the directions. Good luck

thanks to everyone for the reply
the tach is a hd and i bought it from a dealer
i had instructions for it there was nt any specific for my model
i will go back and ask them as vyb said

thanks again
