Hi there, I thought i’d mentioned it before, but yes get the Noahlink wireless from eBay or Amazon, AliExpress etc and the software or the Rexton flavoured Connexx software.
You just need the user guide, but Connexx has a simulation/demo mode, this is a very good idea to do so you can see exactly what the software does and how it works, most of it is self explanatory so quite easy to follow.
Welcome to the forum, great your giving DIY a go, please be sure to research and read the user guides before starting your DIY projects as it’s very helpful for setting up the first time, as you have the Noahlink wireless programming device already I’m sure you’ll be up and running in no time.
