electrical hookup CB radio on 04 TJ Unlimited
Does anyone have any wisdom where to hook up the CB radio, hot wire? Should
I hook up directly to the battery? Any wisdom, schematics, wiring diagram etc would be helpful. Thanks Gus Hrncir, Houston, Texas |

On the earlier TJ's there are two accessory wires fused, taped off, and
marked around the fuse block, behind the glove box. I would NOT go directly to the battery! -- JimG 80' CJ-7 258 CID, HEI 4.56 Gears, Lock-Right F&R 35" BFG MT on 15x10 Centerlines D44 Rear, D30 Front.

Jim, that's exactly where any 2-way radio should be connected, directly
to the battery. I've been involved in building, repairing, and using HF/VHF/UHF 2-way commercial, military, ham, and CB radios since probably '66 and "Basic Radio Installation 101" technique is to always to obtain power for any 2-way radio as close to the battery as humanly possible, if you can't wire it directly to the battery. The battery acts like a big noise suppressor/capacitor and helps a 2-way radio send and receive with as little externally generated noise as possible.

Hi Jerry,
I am sure you are correct, that is the best power available (assuming your ground is as equally good). My suggestion is not "off the cuff", I too have an extensive electrical/electronic background. My suggestion was for a new TJ owner wanting to connect a CB radio for general usage (I assume) which I have done multiple times with success. Now if he wants to drill through the firewall and properly fuse and size the wire, add a linear to talk across the country, then yes go directly to the battery (make sure you use all gold plated hardware too!). :-) JimG "Jerry Bransford" wrote in message ... > Jim, that's exactly where any 2-way radio should be connected, directly > to the battery.

No need to drill through the firewall to pass wiring through it Jim,
there is a large rubber grommet at the top of the driver's side footwell that allows wiring to be passed through the firewall to the battery.

There are two schools of thought on that. You can connect it directly to the
battery and remember to turn it off, or you can connect it to a switched source that is hot when the key is in the ACC position, or ON, this way the CB will be off when the key is off.

Don't forget the fuse as close as possible to the power source.

As Jerry said, the primary reason for running the power leads directly
to the battery is noise suppression, not for high-powered linears.

You could also install a relay between the battery and the CB, wired to be
switched on when the ignition is on. "Jeff Strickland" > wrote in message ... > There are two schools of thought on that.
