I am connecting an after market radar system which does not plug into the cigarette lighter, it has a cable connection for a power source and ground. I am needing to connect it toa source where it will only supply power when the key is in the on position, kind of like the AC. Anybody know where I can connect this to? I really don't want to splice into something and screw it up. I've checked the fuse box and I was not able to find anyting.

Thanks.

 

maybe the power wire for the radio

 

You can just get an add-a-fuse and run it off the 12v ingnition switch fuse under the dash.

 

+1 that would be easyer
