Here is what I did to enable the glove box to be open with key on and engine off and not in neutral. I even added glove box lights so I can see what's insdie at night!
2004 Yamaha with Glove Box light and momentary switch added to bypass glove box neutral safety switch.
Note: This is the way I modified the glove box neutral safety switch for it to be able to unlock without the need of the bike being in neutral:
1] I added an in-line diode to the power supply wire of the glove box switch that went from the accessory box relay (note as item #18 on the FJR1300AS© wiring Diagram which is O/W or Orange and White wire) to the accessory box solenoid which is listed as item #17 on the wiring diagram. This relay is triggered or energized by #15 the neutral switch. The reason for the add on in-line diode to the accessory relay is to prevent voltage from feeding backwards when the momentary switch is energized when the bike is in gear. This feature is used to gain access to the glove box by activating the glove box solenoid without the need of the bike being in neutral.
2] I then used an ignition circuit power source, which I added earlier from an aftermarket fuse block, this gives me the option to gain specific ignition or battery power to the specific accessory circuit only when the key is on or continuous power without the key, engine does not have to be running. This circuit is also protected by a 10 AMP circuit breaker located in an additional fuse block housing I added. The 12 volt constant power is protected by a battery saver that will shut the power down when the voltage is below 11.8 volts.
3] The ignition power source is tied to a momentary switch so the only way the accessory box solenoid will be energized is when both the red button momentary switch and the accessory box OEM switch is simultaneously pushed with your left index finger and your thumb. By pressing down on both buttons, this will allow rider to open glove box while motorcycle is in gear while riding or park without having to stop the bike or put the bike in neutral. The momentary switch is installed so we do not forget that the accessory box solenoid circuit is energized and stand a chance of damaging the accessory box solenoid and leaving the lights on in the glove box. “Lights?”
4] I also added an extra feature that I enjoy, glove box light so I can find what I have in the box when it is dark should I need to open the glove box at night.
5] These light circuits are tied to the Orange and White accessory box solenoid circuit. The beauty of this is that the lights only work when the box is open and or in neutral, or it can be on if you wish it to be in gear by simply pushing the added red button momentary switch next to the glove box switch. This way you will never have the lights on when you don’t have the box open. Lights are only on when glove box is open in neutral or when the momentary red button next to glove box is energized. Very simple but it works.
The bad quality pictures above shows the glove box can be opened with the red button momentary bypass switch within reach of both the rider’s index finger and thumb. The Orange and White wire is the power supply wire for the accessory box solenoid. This is the wire that the diode is installed in-line. The added bypass wire from the Red switch connects in between the diode and the accessory box solenoid along with the power wires to the accessory box lights shown on picture above.
Hope this helps.
