1992 400E Stereo Troubles

[cyberdyne]

I have run into another snag while making repairs.

The 8 pin DIN cable was cut at both ends. I have new 8 pin DIN plugs for both ends but I also managed to cut about 8" of the factory wire from the parts car I harvested the amps from.....but after stripping it back the smaller wires inside are NOT the same colours as the cable in my car.



I am also unsure of how to re-connect the rear speakers. I am able to plug everything else in but I do not see where the rear speakers connect to this amplifier? I suspect it is the two black and white ports on the bottom left of the amplifier in this picture?



The rear speaker wires were cut and had been fed into the also cut off DIN wire.



I am making good progress and I can see the finish line! Once these are sorted out I am in business!

Almost there.....I purchased a reconditioned BE1432 and new DIN cable. I just need to sort out the rear speakers and I should be in business!

Can anyone with a stock speaker system snap a picture of the amplifier end of the speaker wires?

I'll try to remember tomorrow.

Hope these help;

Thanks! That is a big help. It does not appear anything is plugged in to those ports? Where do the rear speakers normally go then?

Sorry I got here too late, but as you've now discovered, it's often a nightmare to return a 1991-1993 stereo back to original, if it had been hacked up to install an aftermarket deck. You have the funky two-piece radio, which has the tuner mounted remotely in the trunk, plus two separate power amplifiers (also in the trunk). The power antenna routes to the trunk tuner, NOT to the head unit. You'll also want to use stock speakers, as the power amps are impedance matched and have built-in crossovers, and it won't sound "right" otherwise. I don't envy you.

BTW - only the 1991-1993 124's had this stereo setup. 86-90 and 94-95 use a more standard head unit with built-in tuner, and these are much easier to upgrade (and therefore usually much easier to downgrade, as installers tend to butcher less wiring).

It has been a bit of a challenge but once all the parts are here it is pretty straightforward!

My only remaining concern is the connection of the rear speakers.

I think I read somewhere that they run to the console fader.

Thanks!

I'll see if I can trace where they were cut and re-join them further down the line.

I can confirm the rear speakers do indeed run into the conduit located in the upper right (when viewed from the rear). Mine have been cut but it will be a simple job to solder them together.

The routing of the 8 pin DIN wire follows the same path but I am still tracing it. It may duck under the centre console instead of the conduit down the passenger side floor pan.
