Hi! I am trying to fit a Tacho (part No A9938043) to my 2011 America. It should be just a plug in job but the tacho is not working. The tacho itself has two plugs and the wiring loom for the console has 3 plugs. When all is connected I have a spare male 2 wire plug from the console loom. (grey/Orange) Any ideas before I send it back???
