The Integrator Mod

This is not a mod I recommend, because I think you seriously sacrifice some safety. Better to have REAL, DEDICATED 21-watt amber turn signals. Regardless, it's something a lot of riders ask about. If you insist on doing this, at least don't get ripped off by paying $100 for a "motorcycle integrator module", when you can buy any trailer light converter at a local autoparts store for $12 and accomplish the same thing. See the links below at sportbikeguy.com for an excellent discussion of this.

Parts

You'll need some basic wire cutting and soldering supplies, but other than that, the only part you'll need is an integrator module. This should cost you somewhere in the range of $12 - $15 at your local autoparts store. Just ask for a "trailer tail light converter". Specifically you want a "three wire to two-wire converter". These are manufactured so that you can attach a trailer with only two lights (used for both brake light and turn signal functions) to an automobile that has three light circuits (one hot wire each for the left and right turn signals, and one hot wire for the brake light function).

When you hook up your trailer to your truck with one of these, you are actually "integrating" the brake light and turn signal light functions into just two lights that are present on the trailer. Since this is exactly what you are trying to accomplish on your bike, these modules are perfect for your sportbike use.

Below are a few of these trailer turn signal modules that are known to work well with the GSXR:

Hoppy #48845 trailer converter module

Remember, no matter which module you use, you do not need to connect your Suzuki running light wires to the module on either side of the module. Do not cut or alter the running light wires - just let them continue on their normal course to the tail of the bike.

Instructions

A Tristate Sportbikes member, hotk4rl, wrote up a very nice "how-to" that you can download, including plenty of pictures.

This mod is very simple, since there are only a very few cuts and connections to make. Almost all malfunctions are due to a simple wiring mistake. So please go through this mod very slowly and deliberately. Be sure to double check each connection before you solder it.

 

 

 

 

 

Refer to the diagram. There are only a few steps to do.

1. Cut off the ground wires to your stock turn signals. tape off those b/w wires . they are not used.
2. The right turn HOT wire (Lg) is cut, and then connected to the module R TURN IN.
3. The Left turn signal HOT is cut and connected to the module L TURN IN.
4. Before you throw your turn signals away, find out if you might need them in order to pass your state inspection later on.
5. Cut the right w/b wire (brake light hot) and tape it off at both of the cut ends. It is not used further.
6. CUT the left w/b wire (brake light hot). The near end (end closer to the bike)is then connected to the trailer module BRAKE IN.
7. Connect the two module OUT wires as shown, to the far , severed ends of the W/B wires going into each tail light.

That's it!

Please note there is no "TAP" connection in this entire project. The most common error people make is to "tap" the wire shown at the red star; this is incorrect. That stock w/b wire must be COMPLETELY cut through at the RED STAR (see diagram).

 

 

 

Here's a closeup of that red star area. Be sure you have cut the left brake hot wire (color White with Black stripe). The two cut ends are shown with circles around them, right next to the star. The cut end near the left tail lamp gets connected to the "L turn/brake OUT +" from the 74209 module. The cut end closer to the bike gets connected to the "Brake +" (orange wire) on the 74209 module.

Troubleshooting the Integrator Mod

If you're having trouble, please check these common errors:

1. IF YOU'VE MADE ANY "TAP" CONNECTION IN THIS ENTIRE PROJECT, IT IS A MISTAKE.
2. If you've used ANY scotchlock side tap splices while doing this mod, it is a mistake.
3. Make sure that you have not disconnected the FRONT turn signals while doing this mod. If for some reason you've done that, the module's behavior will be unpredictable. A malfunction means nothing unless the malfunction occurs while ALL the bike's lights are connected.
4. If you've done ANYTHING to the solid brown (running light wire) it is a mistake. Likewise if you have done anything to the gray wires going to your tail lights, it is a mistake. These wires should not be touched during this mod.
5. If you've done ANYTHING to the B/W wire going to the tail lights (stock GND wire to the tail lights) it is a mistake. That wire should not be touched during this mod.

If you're still having trouble, definitely download the "how-to" pdf file, originally authored by hotk4rl. The photos are excellent, and it may help clear up some confusion. Also there are plenty of other guys who've done this mod who can help. Check into Gixxer.com or Tristate Sportbikes.com and post up your question and you're bound to get lots of help.

"I did the trailer integrator mod, now when my flasher is on, and I hit the brakes, the flasher goes crazy and flashes too fast. What's going on?"

Conclusion

Remember, you are definitely compromising your safety if you do this mod. Numbskull cagers are more likely to see you if you have a huge set of dedicated turn signals with 21W bulbs that flash only when you are turning. If you "integrate" this function into your tail lights, it is very easy for cagers to be confused as to whether you're turning or braking. Sure the mod helps your tail's "cool factor", but you can get rid of those ugly stock turn signals and replace them with other aftermarket options that are much more safe than "integration". Think about this carefully.
