QR25DE ECU/Wiring Diagram - Nissan Forum | Nissan Forums Aug 25, 2009Hey, does anyone have a QR25DE ECU/Wiring Diagram for Altimas/Sentras? In particular I'm looking for 2009 Altima Coupe ECU Wiring diagram. But whatever you have post it up. I'm looking for all the wire colors and what they are for so I can wire in an AEM FIC.
