When tapping wires. I would run straight from the battery. I installed one in my car. I tried just using the cig adapter and my ps2 would not start. It had enough power for the lights but the game disc would not spin. I hard wired to a splitter that has 2 gauge running to. After that the ps 2 works great. This is with the car not running. Micker72 That is an awsome looking install. You have given me some ideas.
