I have the spectre pro ems and bout to hook it up. Just want info before i do to make it easier. whats the best way to tie into sensors and injectors and where? Also best place for grounds and power. I also have nitrous and do I put a switch on it or what? I do have the pinouts and wire diagrams for the car just want to make sure i do this right. Also i was told there is a code for our cars that is different from what comes with it. Anyone know? Please help with how to install. Thanks
