Add A Tach- Splice To Purple/Green Wire?
I'm looking at adding a tach to the Street Bob- I found a few of the old threads but a lot of the images dissapeared and no one gave an positive info, but someone mentioned you can simply splice into the purple and green wire running under the seat and you'd have signal?
Sounds easier than some of the other write ups, but has anyone successfully done this?

I know that pin 3 on the ecm plug works great on the 06 street bob and being the same connector is used in the 07 i would assume it be the same When you open the connector you see there is three tiny blue rubber plugs in a row on the one end. Starting from the end go 3 back it the last open one in that row and install a pin works great. You get the pins at the dealer for 11 cents and i had them crimp it and add wire to mine all for the effort of getting the service guy a coffee while i was waiting.

Where is the tach feed on the speedo? That's the other vague answer I'm seeing. "I just drew everything from the speedo".
Meaning what exatly? Any certain color wires...?

I think it is green/violet wire. The serial data wire that gives your speedo info is the same wire that gives your tach info

On mine, there was an open pin with a pink plug in it on the speedo plug, I think it was the 3rd wire from one end. The service manual's wire diagram should tell you. I got a connector from the dealer just as loopie did and picked the orange/yellow wire for power and a black wire for ground. This is for a cheap J&P Cycles tach.

My 2012 service manual shows the tach just tapping into the speedo wires. No idea what this looks like on the harness. For 2012 tach:
pin 2 white/red CAN high
pin 5 red/orange Battery fuse
pin 7 black/green Ground
pin 8 white/black CAN low
What year / model bike did the tach come from? What part number is on the back of the tach? Maybe someone else can help with the correct service manuals.
Good luck - I'm trying the same thing on my bike.
