When hooking an aeroforce gauge to 12v power with add a circuit u only use ths red wire to do that right? I ran the red wire to my fuse box with add a circuit and had the jumper out and have it plugged into the obd2 port, but when I turn my car on the aeroforce doesn't turn on. Just wondering if I did something wrong. I used 22 gauge wire to connect it to the add a circuit and the wires the plug into the aeroforce and left the green and white wires unhooked to anything and I had the jumper out. Should I use diff gauge wire or plug into a certain spot in the fuse box? Its a 01 grand prix gtp.
