I just did mine today, in about an hour, and connected it to the battery (isn't that why there's a fuse there, anyways?). So far no problems. Plus, there were a couple of good grounding spots nearby.

We'll see what time will tell.

Cheers.

I got mine hooked up yesterday. I still need to put a SWR meter on it. I hooked the pos. to the battery and the neg to a good ground(under the hood). The sound clarity isnt what I expected but this is my first cb so i didnt know what to expect. Some people you just cant understand. Others are loud and clear. Overall i am very pleased.

how difficult is it to lift & re-set the carpeting to run the antenna cable from the rear to the front? what needs to be removed along the way?

also, if connecting cb directly to the battery, does this mean the cb "stays" on after the ignition key is turned off? is there enough draw that the battery could be drained after a length of time?

if connected to the cigarette lighter, which wires should be used?

sorry, i'm just learning to do all this

Its not hard. I just ran mine along the edge and tucked it under. I used 18 feet of cable and had a foot or so left over. If you hook straight to the battery it will stay on untill you turn the unit off. Hope this helps some.

I will be doing this install this evening or tomorrow. So I have a couple of questions.

What do I need to do with the extra foot that's left over?

Also, did you have to unscrew the end that's attached to the mount to push through the grommet on the tail gate??

Thank you very much for your input in advance.

You can easily get to it to plug and unplug the mic (though it does sometimes take both hands), and you can hide it away if need be. Simple, quick and no extra holes in the Jeep.

I used the hole on the side of the dash to run wires straight to the battery so it took me less than 10 minutes to wire it up.


And yes, our JK is filthy. . . just the way it likes it. (???)



Edit to add picture.
I think I am going to leave the connector free like Hip2u77 did.

I just took the grommet out, ran the cable and then put the grommet back in. The extra coax is just loose up under my dash. Im having some issues with my ant that i posted about in another thread. I think its grounded. The continuity between the ant coupler and the mount is 4 olms. I think this should be open. Hope this helps you.

Can anyone post a picture of their wires hooked to the battery? I'm not sure how to hook up power. Red goes to the + of the battery, I know that much, but just wrap it around the post? Does the black go to the - or to some other place? I read earlier in this thread that someone hooked it to another place under the hood.

Sorry for the n00b questions. Thanks very much for your help!

Bob

Bob, easiest way to hook the positive to the battery is to get a little connector that looks like a metal donut on the end. Double check the size of the donut for the screw that connects the battery (the connector will have a red, blue, or yellow plastic thing on it, depending on the size for the wire and donut you are using), and you just trim the end of your positive lead by about a quarter inch, twist the exposed wire together like a rope, then crimp it into the plastic part on the donut. Then unscrew the bolt that fastens the main positive lead onto your battery and put the donut in between before tightening the bolt back on.

As for a ground, I would just find some other wires that are grounded closer to where that negative wire is. If you look hard enough behind the dash, you'll find some other wires (usually black) that look screwed into "nothing," just some bolt in the metal. These are almost always a "ground," and you can just add a ground there as well as you know it is a good ground already. (Again, these will be little donut liiking metal connectors as well).

Sorry I don't have pics. But wanted to give you a response. Let me know if you have more questions and I can help you further. Without pictures, might be easier for me to explain by phone, if you are in a hurry to get it done.

Good luck.

Ok, I think I know what you're talking about. I'll swing by my local hardware store and check out what they have. It sounds like its pretty easy to do.

If I run the hot wire to the battery and run the ground to someplace behind the dash, can I just cut the black wire so I don't have a lot of extra cable? Or would it just be best to tie it up someplace back there?

Thanks for the quick response!
