Just had a radio shop install a 2 way VHF radio for. They put the power direct to the battery. Im wanting to have it only work with the ignition on. I do not want to pay another labour fee after being told its as simple as connecting a wire ( to the one already hanging out the back ) and putting a relay switch on it then connecting it to the ingition wire.

I did a search here for the ignition wire in hoping I could see where it is and what it looks like (color,ect.. ) but the search came up empty.

Anyone have a picture of what the wire looks like and where it is ? Im sure someone has connected a back up camera or gps or something to this wire. Any help would be apprechiated. Thanks

It always helps to have info on what vehicle is being asked about. I'm sure someone can help you now.

If you don't get an answer, PM me and I'll get the info from the stereo shop my business uses for our installs.

Also, depending on how many amps that pulls, I would recommend isolating with a relay. Just use the ignition wire as a trigger. You already have 12v to the battery.

Why not just use one of those "add a circuit fuses"? Plug it in a switched power fuse in the box, and you're set. How many amps are we talking here?

Agree with this, assuming the load is not too high. This is what I would likely do.

Is there an empty slot on fuse panel that is switched that you know of ? Where do you connect the end wire too ? The ignition wire or radio wire ???

That's the good thing about the addacircuit- you don't need an empty spot in the fuse panel. You simply pull one out, stick the addacircuit in the space, and plug the original fuse back in to the addacircuit. It makes 1 spot into 2.

The red wire off the addacircuit is the positive. Splice that to your equipment, make sure you have the other side grounded to body/frame, and you're set.
