My 500SL has had the 1432 removed, and an aftermarket headunit installed. I want to go back to a 1432 sysem

In the back, next to the tuner, I have a power cable, a gray bus cable, two speaker cables, an antenna cable, and a large black cable I cannot identify. The speakers wires, power cable and the unidentified cable are all in a loom together. The gray cable is by itself, and looks just like a new bus cable I have.

The unidentified cable is the same size as the gray bus cable, and has been split to reveal white, yellow, red and blue wires, one of each. These wires have been spliced to wires from the bus cable, and the speaker wires have also been spliced into these.

Thanks for staying with me this far, my question is, what is that black cable and where does it go in the stock system? Could it be the bus from the 1432 tuner going to the amp? Where does it plug on the 1432 tuner? Any pictures of someone's rear tuner with cables connected would be very helpful. Not to push my luck, but if anyone has a photo of the 1432 head unit with all of the wires hooked up, that would also help.

Also, are all of the 1432 rear tuners alike? Would a rear tuner from a 91 300E
fit a 91 500SL? Are the hookups the same? If there is anything I still haven't thought of in my "audio restoration" please let me know.

Thanks,
Roger

here is a pic of the tuner module. The black cable you are talking about is the pre-amp input to the sub amplifier that is under the passengers floor board and should have a 3 conductor plug on it. The gray cable is the data cable to the front head.

Thank you very much for that picture! That answers a lot of questions. Just out of curiosity, what is the inline plug in the bus cable in your picture? Is that the cable setup for the changer?

Thanks,
Roger

Yes, I just did this job on tuesday and added the alpine mp3 cd changer.

I noticed in a different post you mentioned that you can get replacement plugs for the 1432 system, and I need a few.

Here is what I need:

Quan(1) 3 prong connector for line out on rear tuner
(2) 2 prong DIN style speaker plugs for rear tuner
(2) Door and dash speaker connectors

Let me know if you can get these, and how much they will be.

Thanks,
Roger

I have all of them, on your door and dash connectors you are talking about the female 2 pin euro connectors or the male ?

I'm not actually sure what I have going on behind the door. The previous owner had a high dollar system in the car, which was removed before I bought it. I don't know what is in there now, so I figured I would be prepared and replace all of the connectors.

If there are a different types that vary from vehicle to I guess i could wait until I tear it apart.On the other hand if the connectors are only a few bucks apeice, I would rather have a full set on hand when I tear it apart, to minimize down time. So if it is not too expensive, I will go ahead and get both the male and female connectors. Let me know what you think. You can email me at shadel@aracnet.com

Thanks
