quick question.I have a tv in my car and had it all dissconnected for long time. I got everything right except im unsure where the fm modulator hooks to? Any power and ground? Thanks guys.

If you are using a FM Modulator that requires a power/ground hook-up, you'll want to hook power to a switched source, and obviously, the ground to a good grounding point. Then, you would run the audio output from your source (PS2, DVD player, whatever you are hooking to your TV) into the Audio IN on the FM Modulator. After that, just tune your radio to whatever station the FM Mod. is set for, and listen away. If you don't have a readily accessible power source (like, the TV power wire or something else that only comes on with the car on), I would just run a small 20 ga wire up to the fuse box, and tap into a switched fuse. Good luck!
