I thought that I will easily find a forum that will have the wiring diagram and how to wire it and get it working with Simhub (like the rpm gauge there is even videos saying how to wire it and everything in details) but I didn't find anything saying how to wire it so if someone can help I will really appreciate it.
Summarising, please don't assume everyone here shares your interests and knowledge. You have come here looking for expertise you don't have, but don't assume everyone here has the knowledge you do have.
Look in the box for the documentation or the internet for "pro shift light datasheet" (for when to signal the light to indicate RPM/time-to-shift). You clip onto coil 1 for RPM and configure your system for the selected RPM.
