Question about 2002 Harley Davidson FLSTF - FLSTFI Fat Boy

1 Answer

New tach does not work. Instructions are weak

Can't find where the pink wire is supposed to go when adding a speedo/tach to a 2002 Harley Fatboy. Stock has a speedo only. Supposed to be plug and play but that's not happening. No luck in the headlamp. Maybe I'm supposed to pull one of those plastic pins out of the multi-pin plug that goes into the tach. Doesn't give adequate details in the weak instructions that came with the tach.

The Tachometer is tied into the ignition circuit. The pink wire goes to one side of the coil. If there is a plug on the coil, remove the plug and see if there is an empty pin slot in the plug that might match something in your directions. I do know that the pink wire is the "trigger" wire on all Sportsters but I've never installed a tachometer on a Softail. Good Luck, Steve

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

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.

Tach signal wire

The tach wire will be a pink wire under the wire loom leading up to your speedo. It's usually tucked into the conduit. If you don't have it there, then you'll have to run one all the way to the ECM.

Where is tach signal source on my 2006 ultra?i want to wire in a shift light. - thx

The source wire should be a pink wire. The location should be under the fairing. It will have a white plastic bullet type connector on it. I believe it's on the top by the speedo if it's been installed. If not then the pin location on the speedo should be said in the directions, and a long pink wire usually comes with it. You have to pull the speedo plug off and install the pin in the connector.

Cant find the tach sensor on a 2000 1200 sportster

The tachometer is an electronic tach and gets it's "pulses" from the ignition coil. The older bikes had a pink wire that went to "negative" side of the coil. The negative side of the coil is the side the electronic sensor plate in the ignition cavity on the right side of the engine connects to.

When I ride my 2000 fatboy my speedometer doesn't

Try inside the tach on the connector. But also remove your speed sensor on the transmission and clean it. They pick up metal chips from the trans and short out. Also, HD had a bunch of bad speedos around your year. They replaced them for free. Doubtful they will replace yours at this late date. You might end up buying a new speedo.
