Help I have a precision vtec controller for my obd 2 ex but I'm lost I don't know where to get the power from and what wires to splice thanks in advance

you spice into the controller instead of going to the ecu. power can come from anywhere thats 12v maybe from the fusebox or something or splice off the ecu's power. aslso spice form the ecu from the tach wire for rpms. look at a civic schematic for the ecu i dont really like these things they are junk you cant add fuel or anything thier pointless and should just run a chipped ecu.
