Hi, posting for a buddy..he has an 05 heritage. He purchased a used tach from a guy...picture posted. Is anyone able to tell me where each wire hooks? pics appreciated...thanks! Randy

 

If i remember correctly..... on my 99 the red was power, black was ground and yellow was signal from the coil.... I think ???????????

 

Yep, Red and Black are Positive/Negative for power and Yellow is Signal.


That's the exact Tach I have. My bike is an 06 EFI so I was able to connect the Yellow wire to a the Speedo Plug. There is an unused Pin for the signal and then I used wire taps to get the power under the console as well.


If the bike is Carb then it's a different hookup for the signal.


Take a look at these instructions and see if they help.

Yup, that's what mine is.

 

I put tach's on my Deuce and RK back in 01 / 02. There should be a loose red / pinkish wire under the console or a red / pinkish wire in a connector that doesn't have an opposing wire in the mating connector. That's where the red one goes. Yellow is power, black is ground.
