How would i add a Constant 12V+ wire to my truck? Pt.2?

Question

I asked everyone, I have a 1993 Ford Ranger, and i have been searching for the constant 12vt wire, with a multimeter, but i cant seem to find any wires giving anything while the truck is off. Is there anyway a could add a wire, like hook one on my battery, and run it to the stereo, or would the power the battery is giving be to much for the stereo? i have a Sony Cdx-gt100 if that helps at all..................................
Every one told me i could run it from my battery, but i would need to run it through a fuse, if some one could give me a step by step installation, with the parts i would need, that would be greatly appreciated.

Answer 1

ok first find were your going to run it from the engine bay ti the inside of the car usually you can pull out a rubber plug thats around the driverside this goes inside the car it around the gas pedal or the steering wheel well you run the wire through there and then up the dash to were the stereo is next now you can either put the fuse close to the stereo or half ways from your battery to the inside of the car connect the stereo and then after everything is connected connect the wire to the battery it shood turn on if you connected everything right good luck

There was definitely a constant power wire behind the factory radio, so if you can't find it with a multimeter, it probably means the vehicle's fuse is blown. This is more common than not, when the factory plug has been cut off. Before running new wiring to the battery, check ALL your vehicle's fuses, including any fuse box under the hood.

If you have a multimeter, checking fuses is easy. Look at the top of a fuse; you'll see two little cutouts where you can touch your probe to the fuse blade while it's still in the socket. Connect your meter's black probe to ground; set the meter for DC volts and use the red probe to test BOTH blades on each fuse. A fuse with no voltage on either blade isn't a constant fuse, and a fuse with voltage on both blades is good. You're looking for a fuse that shows voltage on one blade, but not the other, while it's in the socket.

If you find and replace a blown fuse, look for your constant wire at the radio harness again.

dude i dont know what u have heard and i dont know if it will hurt it in the long run but i had a 1991 berreta that the stereo had gotten ganked out of so what i did wus instead of tryin to pull out the old wire cuz it wus all cut to were it wouldnt fit the new radio what i did wus run wire from my cd player to my speakers and then i ran a wire through th back of the dash through th part of the door with the hinges throught the hood and straight to the battery it worked fine for me just make sure you turn the power off when you get out cause if not then there is a good chance thatr you will have a dead battery when you go back out but it worked fine for me like that for about 6 months until i got rid of the car and the radio worked fine after that so it should be ok
