I purchased a new/used form an individual there is not install instructions.
Two questions:
1. electrical wiring there is a red/white black what do they attach?
2. how does most builders attach the pitot itself to the mast?
Thanks

Instead of answering just those questions, here's a link to the entire installation guide for the heated pitot: http://dynonavionics.com/docs/support_documentation.html (near the bottom)
