I plan on installing some interior LED lights for my 99 civic Si. My question is where do I hook up the 12v positive and negative wires so that the lights can still be turned on when the ignition is off but when radio is still on? My guess was to hook it up to the 12v line in my deck and hook up the negative to a ground. Help a newb out!

 

LOL.... *coughcoughRICEcough*



How is your radio going to stay on if your igniton is off?

If you're saying that you want the lights to be on when the car isn't running, but you have the key turned to accessory, then yes, you could run a limited number of LED's off the switched 12v lead going to your radio.

However, the proper way to do it would be to run a relay and have the relay triggered by the switched lead & powered off the battery.

 

There are 3 "free pins" on your under dash fuse box, just above the fuses, one of them will be acc. I believe it is one on either side of fuse puller tool.
You will need a terminal like this... http://www.scosche.com/scosche...0-100
Ground to the cars chassis, you will find OEM ground bolts on the lower A piller. 94
