I've had this car for along time and never had problems. I have my motor pulled and i'm respraying my engine bay, and have an AEM ems going in when i'm done, so i'm gonna just go with a brand new wiring harness.
So here's your chance to get a working Wiring harness with an Apexi AVCR already wired in. I only used the Apexi for about 3 months.. it's in great shape - the harness has unknown miles on it, but was working when i pulled it from the car. The harness also has Brand new Coilpack plugs on it ($60) and brand new Injector plugs ($60 - the newer style for the nismo injectors i had 740s) None of the plugs on the harness are cracked or broken etc.
AVCR comes with original box and instruction manual!
