Hey guys, am fitting an aftermarket tach and was hoping to get some advice. When I bought the tach the seller said I needed the adapter for single fire igntion, I have a link for shareaproject that shows a guy fitting a similar tach to an 06 Streetbob and has taken the signal from pin 3 in the ECU, the adaptor appears to be for connecting to 2 separate coils??. I am sure we only have one on an 07 Dyna and the 06 I think would be the same. So what gives with the "single fire adaptor" ??

Cheers.

Let us know how you go a I'd like a tacho too some day.I've seen a few wiring diagrams on line. But not sure myself. Post pics when your done
