I'm hooking up electric fans on my '03 Sierra. I think I've about got it done, but I'm a little stumped on where to tap int a "keyed ignition source." I'm from the school of dinosaurs that used to be able to use a spade connector and hook into an "Accessory" on the fuse block. But I don't see those on my truck. Where have you guys tapped a keyed source that' doesn't cause problems down the line? This is the only thing keeping me from getting this done. Thanks in advance guys!

 

You just need a wire that is hot only when the key is turned on. They are typically pink and easy to find. Or go to an auto parts store and buy a fuse tap. It makes it pretty easy to tap into a key hot source.

 

Thanks for the reply. I'll look into a fuse tap. Are they just a simple tap w/ no fuse in it, or does it still have a fuse with the tap coming off of it? I was noticing that my fuse panel inside the drivers door has fuses where they should be for 4-wheel drive, but mine's a 2-wd. Maybe there's an opportunity there.
