The 950sm doesn't have a Rev counter, I kind of miss it, but the superduke and adventure did. So I've bought a rev counter from a superduke, I'm planning on mounting it in the dash, I've got a fibreglass kit with the intention of making surround and having it sit a bit proud if I can't get it flush. There's a pin on my ecu that sends the signal for the Rev counter, I'm guessing they used the same ecu, so do I just need to connect that up, take an earth and a live from the ignition or will it be more complicated? Edit* Tacho has 3 wires.
