1995 W124 Estate Wagon Audio Wiring Diagram

[MotardMan]

I've searched this forum using several keywords and failed to find a diagram showing wiring colours for the head unit and speakers.

I'm swapping out the Blaupunk the car came with, for a Becker Cascade. The current wiring is chopped up and bullet connector infested... What I need to know are the wiring colours for the 4 speakers, and the head unit 12v, earth and antenna power cables.

I've attached a picture of the current wiring mess and the back of the Becker for reference.

The current block connector has to go..


And these bullet connectors need to go too:


I'll only be sing the lower sockets, A and B for the time being:


Socket C will come into play when I install the underseat subwoofer.

So, can anyone help me out with a schematic please?

Redirects to a dead link. Do you have an alternative site? Thanks for the help!

If you can, post your VIN here

What will the VIN achieve, you got me all interested now!

OK. It doesn't match the car. Bugger.

In for a penny, in for a pound. Not as nasty, and more importantly more compact than, Scotchloks. https://www.amazon.co.uk/gp/product/B07J6SRK1S/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

DVM to help with measuring the **** out of stuff, https://www.amazon.co.uk/gp/product/B01N9TRQI1/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

Expand the DVM probes into connectors and fuses, and be able to clamp the leads on for hands free measuring, https://www.amazon.co.uk/gp/product/B077MF6FB5/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

And this is going ot be SO useful. Can be like a basic DVM, but most importantly will power up stuff like relays, motors, switches, fans, stereos, can also send pulses for testing speakers, and so on. https://www.amazon.co.uk/gp/product/B071LHLSBB/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

And these to replace the horrible ISO ****-up that has been bodged in, https://www.amazon.co.uk/gp/product/B07KRMTFY1/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
So, this weekend, ought to see the stereo in, and some other stuff out.

Wish me luck! I'll let you know how it all goes.
