After putting my new wiring loom in my bike, my tach and speedo backlights failed to illuminate, and my turn signals would not work. Here are the fixes, written for fellow wiring dummies:
1. Backlight not illuminating on the speedo and tach - There is a brown with a blue stripe wire that connects to the black (switched power) in the headlight bucket. Change the connector on the brown and blue striped wire from female to male, and the hook it into the black wire multi-connector, which can be found in the headlight bucket. The problem is that this brown and blue striped wire is female in the headlight bucket, and it must connect to a multi-wire connector that is also female. The wiring diagram shows that there is a male-male wire that allows this configuration to work, but if you're like me, you didn't scavenge this wire from your original loom. This can be found in the exact middle of the wiring diagram.
2. Turn signals not working - On the 6 wire plastic connector in the headlight bucket, you'll notice that the grey wire on one side does not match up with the grey wire on the other side. On the instrument side of the 6 wire connector, push the grey wire's barb down on the blade, pull out the blade, and reinsert it so it will line up with the grey wire on the loom's side. The grey wire comes from the blinker unit and delivers power to the turn signal hand control, which the aftermarket loom prevents from happening. This can be found just above the horn on the wiring diagram.
