I will leave a length of wire hanging off your gauge to which you can attach your LED.
Be careful with the wires though, try and get them mounted to where they wont bend much and flex and break off the pcb.
all this is good for me.
It tests my skills as a programmer for sure. Programming in C to make these microcontrollers conform to your will is no easy task.
I look forward to the time I will be spending in R&D trying to get the shift light working as stated above. It's funny it seems like it will be impossible to do because I don't know the exact word string to make it work at this very moment but eventually I will. So weird to see it like that lol.
It's like an unsolved math problem and requires heavy concentration, but you can do it and when it's done correctly you feel satisfied.
