Tach wiring help
Tach wiring help
So I bought this tach from a member, PN# 67042-95, and its a 3 wire Orange, Black and Pink.
Orange=Power
Black=Ground
Pink=Signal
I have a 2011 StreetBob and I tried tapping into the Lt Green/Violet wire for signal but all I get is crazy needle bounce.
Am I SOL on this tachometer working? Or can I grab the signal a different way?

Thanks guys, I grabbed the tach signal from the Serial Data wire at the harness (LtGrn/Vlt) in the diagram. The needle just swings around erratically.
im not 100% positive but on my 06 the signal comes from pin 3 on the ecm. check wiring diagram for your year and see if it the same

you need the diagram after the main harness connecter to see where it goes, the serial data line is a communication line. it just lets each of the modules "talk"to each other in easy terms

Not sure what tach you have but the stock harness from a low allowed me to install a low rider dash with tac. Plug and play.

The serial data wire won't work on a tach that old, that's what I tapped into but my tach is a newer sporty tach. You may be able to tap into a different wire to get the signal needed for that tach. I think pin 3 at the ECM???

Edit:
Got it working. The pin pushed out a little from the ECM plug. Had to push it a little further through and make sure it clipped into place. All working now.
Thanks for all the advice.

Just to be clear, was it pin 3 on the ecm? I gotta help a friend hook up a tach on his 2010 street bob, and we are a little stumped.
