ACC/12v Wiring Diagram (EDIT: FULL diagram added)
Below is a diagram that I made showing how the ACC signal will be distributed through the car. I have a relay circuit (aux-input mod) in the trunk, I will be feeding it power from the cig lighter. The amp gets a straight ACC signal and the computer gets a switched ACC signal. I set up a relay that switches power for my USB hub/DVD drive/Lilliput since I didn't want to give it a constant 12v or overload the cig lighter. The blue boxes are fuses and the numbers in them are amps.
Let me know if things look good and if my fuses are set up right. I'm using network cable (CAT-5, 24 gauge) since there are 8 wires in each cable. I used it in pairs in some places.
