Thanks Scott. I actually figured out the wire colors already, the only one I am still not sure about is the ACC wire but I am not gonna need it for this project so I don't really care. The real question now is: is there a way to tell if the engine is running or not?? One answer could be tap into the oil pressure indicator and if there is no pressure - then the engine is off. But VX does not have the oil pressure indicator so I can't use that trick. I would like to disable the button when the engine is running so if you press it again it wouldn't crank the engine while it's already on. So far, I haven't be able to figure out how can I do that... so it looks like the button is gonna go in this weekend without this preventative measure. Unless anyone has other suggestions?
