    Arrow Switched Power Wire Needed!

    I have a 2007 Tahoe that I want to hardwire my radar detector into. In older cars, this is an easy undertaking, but I look under the dash of my 'Hoe and see a rats nest of wires!

    Can anyone help me and point out a switched 12v wire I can tap into?

    Thanks in advance!

    That's the hard way. You can connect to you accessory power from your deck, or, you can just run it to your fuse panel and connect it over there and avoid have to take anything apart.

    I went from the fuse box. Not switched power but easy. Try the mirror using this http://www.invisicord.com/

    There are plenty of switched power sources in the interior fuse panel... Just get a mini fuse tap and there ya go...

    Ok, I have a similar issue as I am trying to hard wire my radar detector and Sirius as I dont like the stock XM in the head unit......

    Anyways, I tried about 15 fuses on the panel inside the cab yesterday and none of them were on the switch.....all were always on. Right now, I am using one of the auxilery outlets but I dont want to have to manually turn the radar/sirius on and off every time I get in and out......

    Any suggestions as to specifically which fuse to tap into?

    I drive a 2008 Silverado......

    That doesn't sound right. There should be several in there that are off with the key out of the ignition (DIC & turn signals, for example). I'll have to go out and check mine later.

    Yes, please let me know what you find out. I didnt see any of those fuses you listed on the panel that is inside the cab. I may need to go through the firewall and pull a line from the under hood fuse panel. Thank you for any help in advance.

    Wheadman, I didn't actually get a chance to test power to these, but I looked in my manual & #22,23, & 24 on the inside panel should all be switched power. They are 10A, 25A, and 30A fuses, respectively. Even though you may not have these features, there may still be power to them at the panel. You should be able to use a fuse tap kit and hook to any of these, and just fuse the new wire to whatever you need for the radar detector (10A?). If you decide to pull power from the under hood panel, I am currently using #43 (10A) for a pressure switch with no problems. Keep us updated.

    There should be a bunch of switched fuses in the fuse panel. You should have 2 fuses for the radio, one is switched, the other is not. If all the fuses were hot at all times, nothing would ever turn off.
