So I tore down the bike today to do this swap. I decided I didn't want to try splicing all the wires and try to find the new connector so I figured I'd get the late model wire harness as well. Well, no such luck having it work. There are a few key connectors that are different. All the turn signals use a 2 pin connector rather than bullet connectors, the ECU plugs are completely different as well. There is an extra ground near the thermostat and one connector is different there as well though it's just a ring terminal ground vs. having a spade connector to plug into. So back to square one as in I'll be having to swap just the gauge cluster connector in to the old harness.

If anyone needs any connectors for the late model harness I have one of each!
