Got the Map-Ecu3 from URD and wired it according to instructions. Everything works great, but it does not read the VSS speed input. I know which input on the Map-Ecu3 it goes, just not which ECU pin out on my 2009. Can someone post a 2009 ecu diagram? Or at least a photo of which wire is the VSS speed wire? Trying to use speed as a 4th setting to activate nitrous after the speed my truck shifts into second gear. Thank!
