They went out of business a few years ago and those will not be available. You will need to either take it into a shop or have a good mobile tech come and assist you with this. Most can look at that wiring and figure it out pretty quickly. Sorry that wasn't the answer you hoped for, but when companies go out of business all that material goes with them. Please get back to me if you need more later as all follow ups are included in our fee.
IF you already knew this, then why ask. Just take it to a shop or call in a mobile tech. And ask for a refund here. No problem.
