I tapped into the main harness with my own harness. If you plan on putting an alarm on your bike don't let the wires intimidate you. You'll need the service manual for your year of bike for this. I used the wiring from the ignition, starter, clutch, and neutral light.
The wires are:
Red-Main 12V power
Orange-True ignition when on
Orange with white tracer-ECU ground
Black with yellow tracer-clutch safety switch
Black-Ground
Yellow with green tracer-Starter(cut) key side and starter side go to their connection points on the alarm for starter kill
Blue with black tracer-Neutral light
The alarm requires a negative signal on the neutral safety switch connection but the neutral light sends a positive signal when the light is off. I used a separate relay powered by the neutral light on post 85 with ground on post 86 and 87a. I connected the alarm's lead to post 30 so whenever the bike is in gear with the kickstand down the relay opens the circuit so the remote start will not activate. This way I didn't have to fool around with the safety interlock relay of the bike.
I ran the harness on the side for now until I verify the connections with a test when all the components are in place. I still need to run out and buy a micro switch to simulate a door so I can program the alarm.
