Supporting Me

My goal is to provide as much help to community as I can at no cost.
This site is free to use and always will be, but if you would like to contribute to the hosting/bandwidth costs or buy me a beer you can here!

Also, if you build your own wiring harnesses or use wiring in your projects you can check out my business, YourSpec Wire.
YourSpec is more than just a wire provider. We built an advanced Wiring Project Manager interface that allows you to define a wiring project and add services to each wire like wire marking, stripping, and crimping.
