The ABS issue was sorted but a few days later, apparantly the Japanese RZ does not utilize the "ABS 2" fuse, and i traced my thoughts to where i remember unplugging 2 wires behind the rear seat of the car which, APPARENTLEY (!!!!!), controls the ABS to the rear wheels. My whole setup will change though, with the install of my Haltech E11v2 in a few days time
