So i have everything installed correctly on the 13 button it all works apart from the Fuel tank level. That Green plug that plugs into the module. I cannot seem to find it for the life of me. I have a spare car thats taken apart and i cant find it on the spare e30 either. I have the 13 button harness and everything is plugged in that needs to be. I am assuming this green plug is something thats on all e30s just if the 13 button wasnt selected at time of purchase then the plug was tied away somewhere. Please help.
