Can anyone tell me what the different color wires on the Oem gauges are? I have an 04 if that helps.

 

Bump. I have a VQ35 in my S13. Motor and ECU are out of a 2004 Z(first gen). I'm going to buy a 2004 first gen gauge cluster with pigtail. Need wiring diagram. Cant find anything about what wire colors are what. Any help is appreciated. Thanks guys!
