Post subject:  Where to pull power from for a CB
I just picked up a secondhand CB radio - It's a midland, no frills, came with a magmount center-loaded antenna and mic - hey, it was only $20, what do you expect?

Anyway, it's time to install it - where should I pull the power from? It says it wants 13.8V, which leads me to believe I need to get it directly from the battery. Does the fusebox or cigarette lighter also carry 13.8? I thought they were rectified down to 12V, but I could be wrong (I've always just assumed car lighters were 12V). Suggestions on where to pull power from?

Also - what kind of power connector is that on the back of the CB? I imagine rat shack might carry them, but it'd be easier if I knew the name of it. It's just a 2-pin white plastic connector with a locking clip on a side. Not sure if it's standard or specific to this CB unit.

The CB is going to pull about an amp so the power can come off of one of the fuses, but if possible it's better to go out to the battery. The power outlets come direct from the battery and should be 13.8v. The connector on the back is probably a common type Molex connector; Rat Shack has one listed for $1.99 that might work.

I run both my KJ and XJ cb's straight to the battery w/ an inline fuse. Works fine, no problems.

I use a "add-a-circuit" (the mini-fuse version) to get power from radio fuse (see the fuse chart to identify the location). This way it's only on when the car is running and doesn't drain battery accidentally if I should leave the hand unit on.

Nanette showed me a little hole under the steering column ... this is perfect for grounding my CB. I just needed to get a set of lock washers, nut and bolt and it just bolts right in. I used a couple of flat cable-tie holders to tie the loose wires down. The CB coax runs under the driver's seat, out to the side of the car under the panels, out to the back, out of the little hole in the opening and over and out under the rear swing gate.

Pictures if anybody wants it :)

Glad to hear you got around to doing it! It's like that spot was made to ground a cb. It just fits perfect.

I wired a cigarette lighter plug to my C.B. and it works just fine. No engine whine or noise at all.

Just stuck the wire into one of the fuses.

My CB hangs below my driver's seat. Can't see the numbers without getting out of the Jeep, but I usually don't try to change channels that much. I hid the power wire under the floor mat and up to the fuse box. I ground the CB on the seat frame. If you have a grounding wire, don't forget to ground it.
