Hey all I've looked on Google and also on here, does anyone know of a thread or willing to help me out..im looking to see what wires go from the ecm to the diagnostic port for a 6.7.particularly 2009 ecm..im helping a guy who bought a fummins, 2006 dually with a 6.7 and zf6..its bad.....bad,bad..the truck runs and drives but to say it's a mess is an understatement..the wiring is a rats nest and everything is thrown together..his obd2 port only works sometimes.this is just one of many many things im trying to help him out with..i found the ecm, and diagnostic port pinouts but it's all ran through another channel it's not directly to the obd2 port..im looking for info to make it standalone, and run from the ecm to obd2 port just like my 06 is if that's possible ..i believe pin 1 and 21 on the c2 connector is what I need, can anyone confirm this??
Thanks
Richard
