Single Fire or Dual Fire?
Hey guys I have a 2009 Fatboy, I just bought a autometer procycle rpm gauge and I can't seem to find where to connect my rpm signal wire to. Is the bike a single or dual fire ignition? The coil has 4 wire I can't seem to find which one is gound? Has anyone installed one of these gauges on there bikes? Thanks!

Most probably will be a dual fire, run the numbers on the coil to a google search and you should find it and that'll probably give you the earth/ground post too if not run the same unit for a schematic/electrical diagram.

So i found that its a single fire, checked the wire diagram and these are the 4 wires to the coil. It says connect the wire from the rpm to gound on the coil?

It's probably the "B" post but b4 you wire in to it make sure that the B posts wire is a grounded wire so that it either goes to the negative battery terminal or goes to an earth on the bike somewhere. If it doesn't it's not the one you want but it should be..
