Guide to bypassing the reserve lighting unit

If your Reserve Lighting Unit (RLU) has gone bad but your headlight filaments are still good, bypassing the RLU can keep you on the road past sundown.

Bypassing the RLU is also necessary to prevent headlight flickering when replacing the stock headlight with LED. The lower power consumption makes the RLU think the headlight is blown, causing it to send pulses of current instead of continuous power.

The procedure is easy:
1. Remove the right side cover. The RLU is a black box just under the cover, seen in the first picture held in place with two screws.
2. Disconnect the molex connector between the RLU and the main wiring harness
3. Jump the blue wire to the blue/yellow wire on the wiring harness. As seen in the second picture, that's the left and second-to-left slots on the bottom row of the connector.
4. Completely wrap the wiring harness's half of the connector in electrical tape to keep the jumper wire from working loose and/or shorting to something else on the bike.
5. Do not reconnect the RLU to the wiring harness. It can be removed completely in order to make room for other projects, like a R/R relocation.

Wiring Diagram + annotations * still undergoing revisions, but still more useful than the generic one. Let me know if you find mistakes or think something additional should be added
