blown fuse 2000 deville

Used the orange (maybe a 12 gauge) wire in drivers kick as power source for keyless entry and blew a fuse not being careful. There are two (maybe three wires that are alike in this harness to the rear. Any anyone help me determine what this is? And fuse location. I've looked at every lighting source, radio, light, etc in the car and can't determine it. Also checked all the fuses under the hood. Can someone help?

key cylinder? Red wire? Do you even have a multi-meter?

found out that the autosteering wheel tilt is out. how do i get to the fuses in the rear panel? do i need to removethe seats? accessable from the rear of the car??

Those cars sure do have a lot of fuses! Under the back seat cushion you should find the battery, as well as a large fuse box. Start there as it's the easiest. I'm pretty sure that on the trunk side of the back seatrest, behind the gray carpeting, there might be a few more fuses back there. Go in through the trunk and remove the gray carpet panel to access. Or if you have the owner's manual for the car, look up "fuse" in the index.

I know....fuses and wires aplenty, right? I have a '96, which isn't a whole lot different, although it has the battery under the hood. Anyway, I'd imagine you might be able to find trunk and fuel door back there, I'm not really sure. But the switch on the dash just pops right out, and they're negative trigger (no relays needed) behind the switch. If it's in your budget, and you want to avoid running wires into the driver's door for locks and disarm, you could use one of the databus modules for that car too.
