Yup the red wire will be the ACC wire. Cant remember since I'm not looking at at it (installed it last summer). But go get a test light at the auto parts place or maybe Wal-mart and use that to find the hot wire on the outlet by the ashtray. You cant screw it up, just clip the alligator clip on the test light to bare metal somewhere, this will give you a ground, now press the point of the tester through the wire casing comming from the outlet. Now one of those wires is hot and the other is the ground, the hot wire will cause the tester to light up. YOU NEED TO HAVE THE KEY TURNED TO THE "ON" POSITION TO GET A LIGHT FROM THE TESTER. After you find your wire turn the key to "off" (You will not get a light from the wire). If the light cycles on and off with the turning of the key then you have found your wire. Problem solved.
