Uniden 510 cb installation •  by: Christo Slee

CB communication is a requirement for most official trails runs. It is easy to use and inexpensive communications tool for group travel. We opted to mount a Uniden 510 compact CB in the original ashtray slot in our 1995 FZJ 80.

Installation Notes:

  1. The surround trim piece is removed by sliding the ashtray out, and removing two screws located on either side of the opening.

  2. Remove the 'cup holder' cover (that is the funny opening at the top right hand side) by inserting a small flat screwdriver into the tabs on the upper part.

  3. Once steps 1 & 2 are done you can slowly pull the surrounding trim off from the dash. After this you have to remove the ash tray slide as well.

  4. To install the CB, the two tabs that have the holes for the screws (removed in step 1) need to be trimmed down. The upper and inside lip have to trimmed down about 1/4". This is a try and fit procedure. The fit is fairly tight but that is good since you will not attach the CB to anything once it is installed.

  5. We removed the small metal plates that serve as 'nuts' for the screws and replaced them with normal screws with nuts and washers.

  6. To CB is powered from a secondary fuse box that was installed under the center console. Power for the secondary fuse box is supplied from the 2nd batter. 

  7. You can either install the CB as is, with a 90 degree adapter for the antenna cable at the back. This way  the CB will stick out about 1 1/2".

  8. Another method is to modify the antenna output on the back of the CB. This involves taking the CB apart, removing the antenna connector by unscrewing the lockring and de-soldering the wires. We had to bend the casing somewhat to get it out, or you can cut the case. Extend the wires so that the connecter has about 6" of wire on it.

  9. Once this is done, the CB will slide in all the way to the back and looks like a factory finish.

  10. We used one of the empty switch blanks to mount the microphone bracket too. (You can see this just to the left of the gear shift.) It was drilled and then we attached the microphone hanger onto it. Unfortunately the weight of the microphone made the blank pull out, so we wrapped some masking tape around the tabs at the back. This made for a tighter fit.

Following image is some of the parts used. The fuse taps won't work.

Bend the case like a barn door.


Here is what the final pigtail looked like.


Resealed the case with a metal plate with a hole sized for the coax and sealed with JB Weld


This image shows how the pigtail was grounded to the case. I used a small screw through the rivet in the case. Put a nut on the other end and connected a ground strap with a connector on the end. This was soldered to the coax shield.
