Is there a wire harness and/or kit for a DD aftermarket stereo install for the 1998 CLK 320? (mine has the tape deck with the "phone" underneath it and a 6-disc changer in the trunk)
I'm not sure if it's Bose, but it has components and an amp in the LR of the trunk.
I've searched everywhere and I can't even find any information about it, let alone find a harness. I can get the pin-outs and hard wire it myself if I have to, but I'd rather have a clean install.
I saw someone post that there is a harness that fits perfect, but it's listed as being for a different model.
This is the first time I've ever seem something like this (Metra, Crutchfield, ebay......nothing!)
Hey man, I've been wanting to do this same install at some point. I've never done an aftermarket radio install myself but I figured it'd be a good time to learn on my CLK. Through my research I found the following youtube video where this guys listed what he used as a wiring harness etc. Take a look and see what you think:
I got three minutes into that video and had to stop.
I wouldn't let that guy touch my car. The RCAs he's talking about are supposed to plug into your new (aftermarket) stereo and the opposite end has a harness, which converts the RCAs into regular wires, which then feed the input signal into your stock amplifier (the way RCAs would).
I don't need someone to show me how to wire a stereo. I've been doing stereos for over 20 years. I'm trying to figure out why I can't seem to find a wire harness for this car. I've never seen anything like it. There has to be some reason why I can't find a harness. I don't see any reason why it would be impractical to make one.
Worst case: I'll take an Audi harness and modify it. If it comes to that, I'll do a DIY video, but I haven't bought my new deck yet, so it won't be right away.
Thanks for chiming in though! All help is appreciated.
I've upgraded my head unit three times since 2005, I haven't had to cut the factory wiring harness, so I'm not guessing here - the wiring harness adapter part number you want is a Metra 70-1784. I've had one in my car since forever and Crutchfield sent it to me for free. They currently cost $13. Using this link, you can see the adapter https://pdf.crutchfieldonline.com/Im.../120701784.PDF Insert the amplifier power wire in the slot to the left of the yellow 12-volt constant and you're set. We have an article in The Southwest Star Magazine, page 62, 1st issue of 2018, that shows the install. Digital copies of the issues are at the website and they are free.

That is exactly what I was looking for. Thank you very much!

Like I said it's not something I've ever done but it's what I found in my quick research and it seemed like it worked fine; glad you were able to pull me off a ledge before I went down that path! lol

Forgive my ignorance but in the article on the Southwest Star Magazine, there is no mention of the Metra 70-1784. Do I have to get the 70-1784 in addition to the items listed in the article? From what I understand, the PAC OEM is no longer available.

I plan do do what MarcusF suggested. I haven't read the article yet, but I can already tell that it'll work fine. I'll do a write up or a DIY video on it once I do mine. Hopefully that'll help you out a bit.

Many of the items listed in that article are no longer available. I bought many of the parts when I did the first headunit change in my CLK and just kept reusing them every time I did another headunit upgrade. The wiring harness adapter Crutchfield originally gave me was part number 120701784 and it is made by Metra. They don't list that part number anymore and that specific adapter is no longer manufactured. The replacement is a Metra 70-1784. You'll note they drop the three leading numbers. The new part is almost the same thing. The difference is the pink wire is replaced by a removable blue wire. I also used a PAC SWI-CAN2 and a PAC SWI-JACK. Those two boxes are available on e-Bay, but PAC has replaced them with a better unit; the PAC SWI-RC1.
Again just coming back to this, I noticed on the PDF link for the 70-1784 that it's stated the Red and Yellow wires should be reversed in our application. Is this definitely the case? If so, I'm guessing the removable blue wire that would power the amp should still go to the left of the yellow which is, in our application, the 12 V Switched?

Damn! I totally forgot to update this thread. My fault.
The Yellow (constant) and the red (acc) need to be switched and the remote wire needs to be plugged into the new harness. After that, you should be fine. Here's a thread I made after I finished mine. Unfortunately I completely forgot to do a write-up. It's pretty straight forward though.
MarcusF was right on the money. Thanks again for that!

I like your setup. That DDIN looks good and your idea to associate images with music is great; especially for passengers. Glad to hear that it all worked out well for you; I'm going to stick with a Single DIN for now as I got one from a buddy and it'll at least allow me to get familiar. Just to confirm, the remote wire needs to be plugged into the harness in the spot where MarcusF suggested (left of yellow)?
So I pulled out the radio today to take a look at the Stock wiring harness in relation to the the 70-1784 and I noticed on the stock wiring harness there is no corresponding wire for Switched Power. Do I have to tap into another source for switched power?
On the Instructions for the Metra 70-1784 harness, for our applications we need to switch the yellow / red cables that connect to the aftermarket stereo therefore making Red be Constant and Yellow Switched. My issue is when I look at the stock harness connectors that correspond to the Metra connector, there is no Pin 7 on Connector A that will complete the connection to the Yellow 12V Switched Wire in the image above. Therefore my question is do I need to attached this Yellow Switched Wired to something else for switched power which I assume is needed to power on the aftermarket radio?
Yah...when the weather warms up a bit again I'll go through and check all the wires for 12V ACC but it definitely does not look like one is there. I'll keep this updated when I do check them out.
No. You should be good on the switched and constant wires (if you switched them like MarcusF said). You're looking for the remote wire in the harness that goes to the factory amp. Do that by plugging in your stock radio and testing the wires around the "core wires" (IE: constant, switched, and ground wires). Pick a wire to put the test light on (with the radio off). Whichever wire lights up when you turn the radio on, that's your remote wire.
Constant and switched power come from the harness to the radio. Remote power comes from the radio to the harness.
Take a look at what my stock harness looks like.
You can see the plug "C" has
Pin 4 = Battery Voltage (Constant)
Pin 8 = Ground
Pin 5 = Amp Connection
but there is no pin 7 which would be for switched power.
I have tested all wires with my multimeter and none of them are switched on any of the Plugs. Convicted, I suspect this is a difference between my 2002 and your 1998
Possibly, but you have to have acc power somewhere. Turn the key to the on (#2) position and find all of the wires that have power, then turn the key off and test those same wires. One of them will no longer have power. That will be your acc wire.

Need car stereo help (wire harness).
Thanks.
