I got a GMAX 54S helmet to replace my old AGV that had just worn out. This was about a year or so ago. I bought it mainly for price, but also for the brake light kit I thought would add a little safety to my ride. For my birthday in May, I finally got the kit. After searching for examples of how other people have made this work on their VTX 1300, I discovered there really were none. So today I made my own instructions specifically for the VTX 1300.
My helmet is the 54, but the kit is also for the 67 and 78. Here are some small pics of these helmets and the kit. I use a modular helmet since I wear glasses and prefer the full-face helmet. This is not a pitch for the GMAX brand. This is just information to help someone who owns this helmet when installing the transmitter on a VTX 1300.
1. I started by using the manual on page 1-30. This gave me the location for intercepting the brake light signal. From this point on, I am assuming you have already installed the new light and battery inside your helmet.
2. I removed the license plate and red lens from the back of the bike.
3. Take out the bulb and interior reflector to loosen the brake light assembly from the fender.
4. Carefully thread a slender object through the wiring hole down toward the tire. I used a skinny flathead screwdriver, but a coathanger will do.
5. Tape the transmitter wires to the end of the coathanger (or whatever) and carefully pull through the hole about 2 inches or so.
6. Once the two wires are about 2" out, trim any exposed wire (it comes standard with about 1/8" exposed). Use the included wire clips to attach the yellow wire from the transmitter to the green/yellow (brake) wire on the bike. Attach the white wire on the transmitter to the green (ground) wire on the bike. I did have to cut a slit in the wiring shroud, and it took several attempts to get the clips attached. The brown wire is for the running lights and is left alone. Be sure to test the brakes to make sure you have a good connection. Your helmet should illuminate.
7. Carefully take up any slack in the wire beneath the fender. The transmitter should be dangling under the light. There are several ways, I'm sure, to secure the transmitter under the fender. I routed the device through the wires and then used a zip tie to secure it in place.
8. Screw the light assembly back onto the fender and replace the lens. That should do it. It took me about two hours, including the swapping of the light in the back of the helmet.
