Backoff Flasher

Postby JDEWALRUS » Wed Aug 12, 2015 4:57 pm



I'm trying to wire in a BackOff brake light signal module and can't find a brake light wire to hook into. I'm under the seat but can't find a good wire. Is there a better place to hook in? I could use any help .

Are you wanting all of the brake lights to flash, or just the LED (if you have one)?

I am interested in both solutions, all of the brake lights or just the LED spoiler brake light. Thanks :D :D

It would be nice to have brake lights and spoiler light all flash, if possible. I believe you hooked up the Kisan flash module on your Honda is that a better unit?

I have installed this one in 2 goldwings, 1 VTX, 1 Harley Road King and 1 Kaw 900.
http://www.3rdbrakeflasher.com/brake-li ... 847cac71ab
It's inexpensive, $19.95 + $1.20 shipping, all fittings included, clip one wire connect both ends to the unit, attach unit ground and use instructions to select program flashing sequence. Has 36 choices. I like it and so do the friends whose bike that I installed it on.

I'm picking one up from that same company, just the $25 model that has the time out and pulsing too. I'm an electrical dummy, though, and don't really know where the best pace to tie in would be.

Under the seat there is a connector C-10. It is on the left side and covered with a plastic box like protector. It is fairly wide with a multitude of wires. I unplugged the connector and used a 12 volt test light to probe the pins in the battery side of the connector while operating the brake pedal with the switch on. When I found the wire pin that lit up and went off as the brake pedal was operated, I noted the position and color and went over to the opposite plug (the brake light side) unpeeled the electrical tape back aways, cut the wire, installed the bullet connectors provided in a way that if I wanted to remove the unit all I had to do was unplug it and plug the original wires back together. Really easy. This position operates all the brake light including the spoiler.

Thanks. I looked at the schematic and it looks like the green/red coming out of C10 feeds all the rear lights. Sounds like a good place to tap in.

I believe that this answers the OP's question.

Thanks Gentlemen for all your help. It's great to know that a fellow Goldwinger can get so much great advise to do your own repairs. I wish, I had thought of this sooner. Thanks again.

One comment on the device you are looking at. It says it is rated for only 4 amps, 50 watts. According to the specs for a standard 1157 bulb, you'll be over amps on a GL1500 (4 bulbs). They are rated at 26w, 2.1A each. If you are replacing all the bulbs (1157) with LEDs, then no problem. But I suspect standard bulbs will cook that flasher in short time. Even if they come in at 2A, you will be at the outside limit of the devices capacity. Just a suggestion. I used the Signal Dynamics Back-Off XP device for the same reason. It is rated at 10A, and is encapsulated in a nice heat sink to handle the load. I later replaced the 1157 bulbs with LED 1157's.

Hmm, good catch. I didn't even notice that. I can't switch to LEDs at the moment though. So I can pick up the Back-Off XP and then convert to LED later or grab the one I was looking at and maybe just wire the spoiler lights until I can convert to LED. What to do, what to do...

I have converted the brake lights and the reflectors in the rear to the LED strips as documented in the How-to section. I forgot to mention that. In this configuration the whole back flashes when the brakes are applied. No problems to date.

I was told by Back Off tech today that I can't tie my Back Off XP into my led spoiler light because it has constant power to it as a running light. Must be true because after wiring it in it won't flash. Was told to use trunk brake lights but haven't tried to cut more wire yet. This has been a real crazy project.

This may help regarding the hookup to the spoiler light. I have a Back-Off on my bike and it is wired as such. One flasher circuit feeds the main brake lights (5 flashes / on), the other circuit feeds the spoiler (4 flashes / on / 4 flashes / repeat).

The problem is that the spoiler is fed by a single 6V/12V source. 6V for running mode. 12V for brake lights. You can't just feed the Back-Off 12V signal to the spoiler, as it will back feed into the circuit. The solution is a relay installed between the 6/12V source and the spoiler, and between the Back-Off signal and the spoiler. I can't tell you which wires I cut into to accomplish this, as it was quite a while back. But it works flawlessly. The result is flash patterns on all brake lights, main and spoiler, with 2 different patterns.

You will need to find the wire that feeds the spoiler, after the OEM 6/12V signal point (device), and cut it. The 6/12V source connects to the normally closed (NC) contacts of the relay (#87a), and will supply the 6V to the spoiler for running light function. The "spoiler side" of the cut wire connects to the output side of the relay (#30). The main OEM brake signal connects to the relay (#85), as well as the "red" wire input to the Back-Off. The (#86) terminal of the relay connects to "ground", as well as the "black" wire from the Back-Off.
I used the "red/white" Back-Off wire to feed my main brake lights (5 flash/on) directly. The remaining connection is the "white/red" Back-Off wire to relay terminal (#87) for the (4 flash/on/4 flash/repeat) signal, that acts as your new 12V spoiler supply.

Operationally, while driving, the 6V running light signal is fed through terminals #87a to #30, to the spoiler light. The main running lights have not been modified and act as normal. When you hit the brakes, the "red/white" Back-Off wire sends its signal direct to the main brake lights. Simultaneously, the relay trips from its normally closed position to make the connection from terminals #87 to #30, feeding the Back-Off "white/red" wire to the now isolated spoiler light, allowing it to flash in the brake flashing mode.

NOTE: I did not use the optional "yellow" wire connection of the Back-Off.

The relay I used is pictured, as well as the part number and mfg.


I got confused just writing this up, so if it confuses you, I'm not surprised. But I checked my description, and think I got it right. The drawing is from when I installed it for my own reference. But I hadn't included the relay numbers when I drew it up.
