Alright, so I have so many plans that I need to catch up on some small stuff. With that said here is MY install!

First off I got the Cobra 18 WXST II

There are 2 versions made.

Here is the first one



And here is the new and improved version,

The Cobra 18 WXST II



Improvements on the later model include

-10 NOAA Weather Channels
-40 Channel scan
-Dual Channel watch
-Instant channel 9 and 19

Here is what the back of it looks like



There are 3 wires coming out of the back, they are power, ground, and memory



I cut them all off



here there are, separated from their mother....



I stripped them and threw some pins on there

I wanted to make my own harness and make the install as clean as possible.

Notice I snipped off the inline fuses? Well after the above plug, I ran those fuses someplace else because I did not want to dig through my dash to get to them. So, the negative continued on back toward the battery.

The power and memory went to a different kind of fuse holder.These are really cool. the top screws off and you throw a fuse in there.



Took a step drill and drilled 2 holes



I did have to do a little modifying which included drilling and cutting this part on the inside



So the power and memory went to and from the fuses back to the plug where it met up with the ground wire once again

I tapped the ground into the existing ground, and (not according to this pic), I tapped the power into the cigarette lighter power. The fan comes on whenever the key is in the acc., running, or in the on position. I almost always run at least the stereo, and I run the CB while I am in town to talk to local X friends.



Here is a better Idea of how it is set up.



From that plug, I ran all the wire through plastic spiral casing. At this point I was all out of properly color coded wiring, so I tied 2 loops in power, one loop in memory, and no loops in the ground



So I mounted the fan right on the side so air is drawn through.



Finally I routed it through the dash, the grommet, and the eng. compartment to the battery. You will see the three ring terminals going straight to the positive and negative. Of course the memory and power went to positive while the ground went to negative.





At this point, I disconnected the plug from the back of the CB. The reason I did this, is because I wanted to mount it in the dash so I had 2 single DIN consoles in the stock location.

Ok so my goal was to get both of these consoles to fit in the exact same spot as the old DVD player

There were A LOT of small, tedious things that I had to do to get this to work.

Drill another hole in the dash.....



I also bought two of these little piece from a stereo shop,



and cut them to fit. I HAD to mount this diagonally for this to work.



The CB doesn't come with that hole that the knob is screwed into. I actually had to take the casing off of the CB, and drill and tap 2 identical holes on either side, so it mounted to the bracket. I could see all of the circuit boards and everything. I also took the casing to the grinding wheel and cut a triangle on the top and bottom of the casings on either side so that I could access this hole.

NOW the bracket goes on.......



Next, I finally installed it! It took me quite some time to get all of the stereo put together and installed but it works perfect.

I mounted it and threw it all back together. Here are some pics of the final product.





and a close up of how clean the fuse mount went.



SPECIAL THANKS TO (in no particular order) Co-WOODY and GT GALLOP for the great advice and the hours on the phone helping me with my obsessive compulsion for trying to make it as clean as possible! Thank you to everyone else who helped me on the threads as well!!!!

Hope you enjoyed!-James

As far as the antenna and the coax go, I went super temporary in waiting for other mods.....Yup, can't open the hatch....

Where does everyone have their Mic mounted?

Alright, so I never showed you the coax or the antenna on mine. Mainly because the first install was super temporary.

Here is my Permanent set up. I think I am going to strengthen the mount but so far, no problems even at highway speed.

I bought a large Firestik base with a HD spring. The antenna is the 3' with tunable tip.


I removed the stock antenna and mounted this in it's spot. Here are the 2 side by side to compare height.



Here is the assembly pre-mounted:

3' tunable tip firestik
HD spring,
Firestik wide base for movement,
a 90 degree coax elbow,
3' coax
then it goes to a splitter (black box shown)-This splitter uses the CB antenna as the AM/FM antenna. You can see it has a coax output and a regular antenna output. You plug the antenna into the stereo and the coax into the radio. You can tune it with a pen screwdriver. YES, THIS MEANS THAT THE CB ANTENNA IS ALSO MY radio antenna


I ran the tuner splitter/tuner straight to the glove box


Looks good and hold up well


edit to add:I ended up removing the black knobs that i have there. In the final install it got in the way too much. I used a couple of metric screws and some fender washers instead. I filed just around the screws and it looks actually stock it turned out so good. I had to trim the bevel trim on the stereo to get it all to work but it is working and working well.

That is a stellar write-up! I thought my install was aggravating just running the antenna cable to the roof. Just toss the mic over your rear-view mirror if you don't want to drill into the X. If not just buy a mic mount, it is a little 3-prong piece of metal that has 2 or so screws to hold the back tab on the mic. Hope that helps
Great writeup. I didn't want to drill my dash so I velcro'd my mic holder to the dash, or just velcro the mic to the dash. There are also mic holders that hang off the mirror that can be bought at truckstops.

I am impressed with the Cobra 18 WX ST II. It works so much better than my previous CBs.
This is the only CB I have ever owned actually, so I have nothing to compare it too, but the price is right, (especially with an e-bay auction) and the single DIN size is EXACTLY what the CB manufacturers have needed to do. As far as the velcro, I will just have to check with a truck stop. I work for a trucking company so I could just ask around.
That is awsome. Thats what ive wanted to do but im really bad with electrical stuff. Looks great. Maybe someday you can help me lol. Where are you located by the way.
So the memory and power wire both go to the positive terminal? Or is one supposed to go the pos terminal, and the other go to a power line that isnt active when the key isnt in the ignition?

I ask this because i got the exact same CB for christmas. I casually read through the directions, but didnt read them in detail. Im waiting to install it untill I get my shrock rear bumper.

I just installed the same CB in my 07. The red goes to switched power and the orange goes to always hot. I cheated and tapped into the adapter harness for the stereo.
Here's how mine looks:



I just drilled the factory stereo brackets (one hole each side). Let me know if you want more info.

They both go to positive. You will not drain the battery if that is your concern. The CB has to be turned on to do that. Even so, I have heard of it being left on overnight numerous times and I have done so myself. not a problem

The problem that I have heard with running the wiring to some place else other than straight to battery is whine. The CB will whine in linear congruence to the RPM. Why are you waiting for your bumper to install it?

Personally, I try to do only one mod at a time (which never works out) so that I can put more concentration on each individual install.
proabsince the rear bumper has a cb ant mount..... i guess he dosent want to try to mount the ant somewhere else and then when he gets the bumper have to move the setup...... just my $0.02 i love the install and i might end up doing it sooner or later......
WOW looks damn good. im getting a cobra 25 ltd wx today..but have not idea where to mount it or how to set it up lol..plus i really like the idea of how its in ur dash.i wish i could do that

Thanks!

Why cant you do that?
idk i cant find a place for the cb right now...and i cant find a place to put the antenna without makin holes.. after i saw ur setup i had enough guts to take it out and u kno where u have ur fuses...i installed my bass knob there for my speakers.. lol it came out really clean and i was really happy i did it myself...
You can buy a bracket which mounts outside for the ant. You can do it without holes. Why don't you add a fuse panel?
what would i need the fuse panel for? i mean ive had a cb before and the fuse hasnt really gone out.. i have one bass knob there and am thinkin of another idea for the other whole
Well when you run a lot more accessories, it is a good practice to also have a separate fuse panel. When you are only running about 2 or 3 more accessories, then you do not need to.

What's wrong with running the CB from under your seat?
i like to see my cb. lol want to show it off..
Right over the center of the dash works great. You can buy velcro that works perfectly
