Sorry for the delayed update, I have been pretty busy at work. My neighbor had contacted me about turning the VSP off, which is how I found my way into this project. I have a reliable source for the factory Nissan switch at a cost around $20 with shipping. I am looking for a closer source to possibly drop that price in half. I have tested the switch and it works perfectly. I have a few sources for the connector and terminals, but I am attempting to find a local source that doesn't require a large minimum order. The pin allocation for the switch is as follows:
2 VSP Indicator Light (Trigger from VSP Control Unit)
3 Ignition +12V Supply
4 Illumination Ground
5 Illumination +12V Supply
7 Switch Output (Trigger to VSP Control Unit)
I will try to get everything setup this week and hope for a shipment to arrive by early next week. I'll write up an install procedure and make a how-to video. Thank you for your patience.
