Radio Harness

I have a 2002 Sahara. I am considering a new radio receiver. Does my year model have the dual plug wire harness design or the newer single plug design? Thanks

Try this. It may help. I have an 01 but can't remember. I know it was simple.

Thanks for the reference to that product. But I am buying a new head unit and need to know if it's a dual plug harness or single plug style I should select. I am changing my dash to accept the later rounded corner style radio chassis but need to know which harness to choose.

Thanks in advance for any input.

If your just changing the plastic centerpiece of your dash to reflect the rounded corners of the stereo hole, your wiring will not change. You should still need the 2 plug setup. If you were putting in a newer OEM radio to match the rounded corner stereo bezel, you would have to custom make the harness. Newer radio=1 plug, Older radio=2 plug. Some Sony units from Quadratec are plug and play. They are already wired with correct plug.You would just have to specify that the radio installation kit needs to be for the newer style dash piece.
Hope this helps!

Easiest way (and often cheapest) is just to order from Crutchfield. They have real people to help who actually know their stuff. They will give you the right answer the first time. They also have everything you need (wiring kit, dash kit, and detailed instructions with pics of installing into your vehicle). From a satisfied customer over many, many years, since before internet ordering!

Thanks guys. I am installing a 1.5 din radio with nav screen, and it's only offered in the round corner style (so i am changing my dash bezel) It does, however, offer the dual plug wiring option. I just wanted to confirm that it was indeed a dual plug set up.
Through my research on this subject I found some conflicting info that said in 2002 wranglers went to single plug wiring but still retained the square radio chassis.

Just trying to order the correct wiring option on this unit. Thanks.

Simple comment, why not pull out your existing radio and see what you have? It's easy to remeove.

Neil is right - it' easy to remove IF you know the secret for the security bar on the back of the radio. Access the nut by removing the glove box. I seem to remember it being a 10mm nut. But I had a couple beers that night...

Mine is a 2002 wrangler X. I would guess you have the same harness (it is a 2 plug on mine) but just to be sure pull the old radio.

this link should help out on how. it's pretty simple though.
Jeep Horizons :: TJ Stereo Install

READ THE WHOLE THING before you start pulling on the factory radio. There is a nut in the back that bolts it to the security bar and ground.

I suggest ordering the harness and a mount plate for your vehicle from crutchfield. It makes it so much easier. You can get a generic mount plate, or a vehicle specific one. I got the wrangler specific one for mine (i put a single din in) and it fit perfect. They usually include a master sheet with how to dissasemble the dash and such for free.

After that just match up the wire colors and splice the wires together. If you have any questions on wires message me or something, I literally did this about 2 weeks ago. Only issue I really had with mine is the security bar had to be bent into the dash a little for the radio to have enough room as it was a little longer than the factory one.

Also since jeeps see a lot of mousture if you are out on the trails, don't waste time with crimp connections. Just slide some heat shrink tube over the wire, then solder it, then slide the heat shrink back over the connection and melt it in place. Takes more time, but it keeps moisture out a lot better than crimps.

As far as the round vs square dash, I think that didn't change till the 2003 model and forward. I forget which is which, I don't know wranglers well yet. From what I could find so far, 97-02 had one dash style, 03-06 had the other.

Sorry for the long post, just trying to cover all the problems I had at once so you don't have to deal with the same mistakes I made.

After looking at that link I put in. The one shown is for the rounded style newer TJ's with a single plug.

You should see a square looking style, and 2 plugs. 1 grey, 1 black.

But the steps are the same. Except you shouldn't have to unplug the climate controls, mine just swung out of the way toward passenger seat after I pulled the bolts out.

There's two nuts on top of the dash, on either side of the defrost duct, that hold the bar in. Did you attach your new unit to the bar?

No i couldn't get it to line up right, I just bent the bar back a little so it would seat all the way in the dash. And I used a specific fit mount plate. I will probably just put one of those tuffy security boxes in later or something.

Nobody messes with cars on base where I work, too many cameras. And if they try to get in my garage the alarm will wake me up before they get anything done.

Funny side note, my jeep is the only thing that fits in the garage so my wife can't park her truck there. It's all mine.

That's why I just removed the bar. Two nuts and it lifts out. I may drop it back in though and see if I can make it line up...

I have my bar hooked up on an aftermarket radio head unit.. A little work in the vise and you can make it work fine.

I just left it in, it made a good spot to secure the ground wire from radio to ground strap from the jeep. Just found a nut that fit on that bolt in my parts bin and tightened it all down.

I wish I had known about the glove box trick though, sounds easier than going through the hole behind climate controls.

Thanks for all the input, guys. Sound like I have the dual plug harness. I went to pull my radio just to verify but having difficulty getting dash bezel removed. Didn't get very far...couldn't even get the top tray removed. Tried to gently pop it out but dash felt like it was about to crack.

That's weird. That top piece should pop right out. try starting at the corner and try to get one pin to pop out, then slowly work your way down the side and around.

The write up in the link I posted is pretty descriptive and had some photos too. It should get you as far as getting the radio out. This mentions pulling the climate control panel to get to the nut behind the radio, but try the glovebox method like Geoff mentioned, and you can probably save yourself that step.

That bezel (or most any plastic dash panel) can be intimidating if you haven't done it before. At least you're being cautious

I removed the climate control and the glove box. One hand in through each..
FWIW, I'm seriously considering taking mine back apart and putting the stock support bar back in. Not sure how it will line up with my head unit, but rest assured I can make it work.

I only left my support bar in because it made a good spot to bolt the ground securely to the ground strap. Would have worked without it, just made the wires a little neater without hanging around loose in the dash
