I would love to know if I could use a non rev up 6mt 350z harness in my 04 G35 coupe 6mt. I really need one and I cannot find an 03-04 g35 coupe 6mt harness anywhere on ebay,

 

I want to say yes, but I'm not totally sure if the grommet is different going through the firewall or if the overall length is a little different, the oil pressure sensor will be different though since the 350Z actually has a gauge for it not just an idiot light like the G35.

I'm almost sure you can also use the engine control harness from any 2003-2004 6MT, sedan or coupe.
