CBR954RR LED Turn Signal Flasher Relay
So, I have a little experience to share...
I added a hotbodies undertail to my bike (02 954), which swapped the rear signal bulbs to LEDs. This sped up the flash rate, which didn't bother me too much.
Recently I went down and jacked my front turn signal. I decided to replace the front ones with an aftermarket LED set. Upon trying them out, I found the signals no longer flashed. I went online and did some research and found that this is caused by the LEDs not drawing enough power from the circuit. The two options to fix the problem are adding power resistors to the circuit, or replacing the turn signal flasher relay.
I read that the resistors can cause excess heat, plus they need to be spliced into the existing wiring. While slightly more expensive, the description of "plug and play" drew me to the aftermarket relay. The person I bought it from on ebay had it listed as plug and play for the 954.
I'll save the extensive details, but here is a brief summary:
The stock relay on the 954 is integrated into the instrument panel. The only way to add an aftermarket relay is to disconnect the wires running to the stock one and connect them to the aftermarket one. The best place I found to do this was after the wiring harness located in the pocket created by the lower, upper and inner left fairings. There is enough exposed wire so that if you ever had to hook the stock relay back up, you could. The two wires you need are the White/Green and Gray wires coming out of the blue wiring harness. I clipped them about 4 inches from the harness. You will be clipping between the harness and the section that goes to the back of the bike. I connected the aftermarket relay to the wires heading to the back of the bike using some 18-22ga insulated disconnects. The nice thing about the disconnects, is that you can switch them easy if you reverse the polarity and if you ever want to reconnect the stock relay, you just crimp 2 more disconnects to the harness side. 4 hours later I had a working turn signal circuit and two new LED signals on the fornt.
If you have any questions about how to do this, let me know. I would hate to see someone else go through all the bull**** I did with the same problem.
