If you are going to install a new ignition unit, all you basically need to know is which wire is the "HOT" wire. Disconnect all the wires to the coil, turn the ignition switch on and use a test light to find the "power" wire. Once you know which wire this is, you'll need the wiring schematic for the particular type of ignition unit you're installing on your bike. Usually, if you got the website for the manufacturer, they'll have "installation instructions" under their "Technical" section. Usually, with a dual fire ignition system, there are only three wires to hook up. Good Luck!

I have not removed the turn signals from a model this late. There may be a nut between the fender and the fender strut. You may have to remove the fender to get the turn signals off.

I would not splice any wire due to the fact that Kuryakyn, Drag specialties, Custom Chrome and many other manufacturers has direct plug in L.E.D. tail light assemblies for your particular motorcycle.

Use an ohm meter to verify that the black wire is indeed a ground (earth). Put the meter in R X 1 and touch either meter lead to the black wire and the other meter lead to ground. The meter should read less than one ohm.

Now, turn the ignition switch on and the headlight on low beam. Put your meter's function switch in DC VOLTS, 20 VOLT or greater scale. Connect the meter's black lead to ground. Touch either the red or the white wire with the red lead and see if you have voltage. Which ever wire has voltage is the low beam power wire. Then switch the light switch to HIGH beam and again check the wires, the "hot" wire is the HIGH beam power wire.

On your new light, you should have a wiring diagram telling you which filament is the low beam and which is the high beam. If you don't, just wire it up and flip the "high/low" beam switch and see if it looks right. If it doesn't, switch the wiring. The new light should have a ground somewhere as well. Since I'm not familiar with this particular light, the ground may be a body ground that relies on physical contact when bolted on the bike.
