Thanks Ben. Great to hear from a buyer. Sorry for the typo. Typo fixed, thanks.
It illuminates the VSP warning light only when the ignition is on. It drains very little energy. It seems to be an important feature because it's pretty dark after sunset. My passenger and I now have an easier time locating and pushing the button.
I use a 10K, 1/2 watt resistor. Simply push this pin into slot
#14. This puts out about 1.2mA to the LED. If you like it a little dimmer, try putting 1K to 5K resistor in series to the wire.
How to build a night VSP illuminator from scratch:
Parts needed: 1 female-male Dupont 20cm connector for Arduino. One 10K-15K resistor 1/4 or 1/2 watt.
1. Remove the cover/housing from the female Dupont pin.
2. Fold the resistor legs then insert the resistor legs into the female Dupont pin then crimp. (Crimp the actual Dupont pin itself using a crimp tool.)
3. Electrical tape or shrink-tube this part of the resistor leg and the crimp.
4. With a diamond file, file the tip of the other male pin to a 45-degree angle. (This will let you insert the pin into the VSP connector.)
5. Unplug the VSP connector from the VSP control unit. Push the male Dupont pin along its edge into slot/position
#14 on the VSP connector. Rotate the pin then plug it back in if it won't go in.
6. Clamp or screw the other end of the resistor's leg to ground, right below the VSP control unit.
7. Plug the connector back into the VSP control unit. Turn on the ignition and the picture of the little car should lit dimly.
Compatibility Info: 2011, 2012, 2013, 2014 Nissan LEAF service manual shows that pin
#14 is for the VSP warning lamp and this mod should work. If anyone has the 2015-17 service manual showing pin
#14 being the VSP warning lamp please let the forum know. This will help the DIY members out a lot.
