Jeep
TJ Stereo Install
In this write-up
I'm removing my factory
tapedeck and installing an aftermarket CD/MP3 player - the Kenwood
KDC-MP919.
Here are the
basics for replacing the factory stereo with an
aftermarket CD player in your TJ.
Items needed:
- phillips head screw driver - for all trip panel and mount screws
- 10mm 1/4" drive socket and ratchet - for disconnecting the
factory
stereo's theft deterrent bar
- flashlight - helping along the way with seeing into the dash
- soldering iron
- solder
- heat shrink tubing
- OEM wiring adapter
- faceplate adapter
**WARNING** unless
otherwise directed, disconnect the negative
battery terminal
during the entire installation process. **WARNING**
1. Starting the
wire harness
The best route to go
is to purchase an OEM wiring adapter for your
Jeep. This will keep you from having to cut off the factory stereo
connector. In the future, you may want to sell the Jeep (for a
different one, of course) and then you could put the factory stereo
back in. These adapters can be purchased from any car stereo store for
about $15. Both the adapter and the new stereo will come with a diagram
showing what each colored wire is and what it's supposed to be
connected to. Slowly twist connect each wire on the adapter to it's
partner on your new stereo harness and then cover it with a piece of
electrical tape. This is just temporary so you can verify that it's
connected properly.

2. Disassembling
the dash
First off, you must
remove the dash upper trim panel. This panel just
clips into place. Use your fingers to grab it at the far front left or
right corner and gently pull up until it pops out of it's clip. Work
your way down the panel pulling it out of the clips as you go. You can
just leave it lifted up and laying against the windshield or remove it
all together. The dash center trim panel is removed by unscrewing the
two screws that hold the top of the panel to the top of the dash. Once
these two screws are removed you can slowly pull the panel away
starting at the top. This panel uses the same style of clips as the
upper trip panel so you'll feel them popping off as you go - there are
a total of 4 clips.

3. Removing the
factory stereo
The factory stereo is
held in place by four screws in the front and one
nut in the back. The screws are in plain site but the nut is a little
more difficult to get to. The easiest way is to swing the climate
control panel out of the way. Remove the screws holding it in place and
then disconnect the two connectors for the left and center control
knobs. Leave the right one connected as it has all the vacuum lines
going to it. You should be able to swing it down and out of the way so
that you can reach into the dash under the stereo. Now, you will need
the 10mm 1/4" drive socket and ratchet for removing the nut from the
theft deterrent bar. You'll have to feel around to find the nut - of
the three holes in the theft deterrent bracket, the nut is in the
farthest hole to the right. Loosen and remove this nut and the stereo
will be free of it's mounts. Disconnect the antenna and the factory
wiring harness and remove the stereo completely.

4. Testing your
new stereo and it's harness
Take you new stereo
and connect the harness to it's connector in the
back. Now connect the other end of the OEM adapter to the factory
harness's connector. Reconnect your battery and turn your ignition to
accessory. You should be able to operate the stereo and all the
speakers should be working too. If everything works as it should, turn
off the ignition and disconnect your negative battery terminal again.
5. Permanently
connecting your wire harness
Since you are
satisfied that you have everything connected properly,
you'll want to set up the harness for a more permanent installation.
Before you start soldering wires, cut all of them to the same length on
both of the separate harnesses. This will make it much more compact and
easier to tuck behind the stereo into your dash. I grouped everything
accordingly - I would slip a piece of heat shrink tubing over two wires
(such as the negative and positive wires for the left front speaker)
and then another piece of each wire individually. After soldering each
connection, shrink the tubing over the connection. After both wires are
soldered and insulated with the tubing, slide that first piece over the
two connections and shrink that together. It makes the harness much
neater when it's finished. You can see that by making all the wires the
same length and then grouping them together it kept the harness very
clean and uncluttered.

6. Mounting the
stereo to the faceplate adapter
The faceplate adapter
is what you mount the stereo within. It keeps the
stereo from bouncing around while it's sitting in your dash. Keep in
mind - the sturdier it's mounted in this adapter, the less likely of
having your CD's skip. I purchased the faceplate adapter at my local
car stereo store for around $15 - just tell them what year and model of
jeep you have and they should have it in stock. The directions with
these adapters are pretty thorough - just position the stereo into the
brackets and attach it with the provided screws. Make sure you use the
screws that came with the adapter. They are designed to be just the
right length. Screws longer than those provided may thread into the
stereo's chassis too far and damage sensitive electronics or mechanical
linkage. **I neglected to take shots of the stereo at this stage - but
when I install my amp next week I’ll take shots while the stereo is out
again and post them accordingly**
7. Final
installation of your new stereo
Connect your new
wiring harness to the stereo and then to the factory
stereo connector. Next connect your antenna plug to the back of the
stereo. Gently tuck all the wires to the side and/or below the area
where the stereo will slide back into. Once the wires are clear, slowly
slide the stereo into the dash. Take care to watch the wiring harness
to ensure it doesn't get jammed or pinched behind the stereo. Once it
is sitting flush, install the 4 screws into the front of the faceplate
adapter to hold the stereo tightly against the dash. At this time you
can reinstall the climate control panel. Connect the two connectors
that were disconnected earlier and remount the panel with the two
screws.
8. Reassembling
the dash
Reassembly is the
reverse of removal. Start by lining up the top of the
dash center panel with it's two holes at the top of the dash. Then
slowly press the panel into place allowing the four clips to seat
themselves. The panel will sit flush with no noticeable gaps around the
stereo faceplate, the climate control panel, and the sides of the
panel. Next install the dash upper trim panel. Start by seating one end
into a mounting clip first. After one clip has popped into place, work
your way back down the panel seating the remaining clips until the
panel is nice and flush.

9. Time to sit
back and enjoy your handiwork
Reconnect the
negative battery terminal and try out your new stereo.
It's guaranteed to sound better than the factory stereo that you just
removed! later...
