I'm installing a new Jvc KD-HDR1 . I'm told I can't get a new harness plug and need to know which wires on old plug will connect to new unit. Note; I'm not using power antenna, I disconnected(broken) Old unit has 4 wire plug: red blue black and brown on one plug. The speakers have just a left and right plug but 2 other sets loop out from the harness. I have 6 speakers 2 rear deck,2 door, 2 top of dash. I'm an old stereo guy from the seventies . All help appreciated!

the w124 service disc will have it available on ebay or at the dealership

I doubt that radio wiring info is on the W124 MB service manual CD.

Go to beckerautosound.com, and search the car audio folder on this forum. There are many threads about changing radios in the 86-93 124 car.

Its on all my service cds...

Call Jim Laplant. 404-277-9383.

He knows all the Mercedes audio wiring color codes with his eyes closed, seriously.

He's in Atlanta.

He can also tell you where to get a plug n play harness for your car so you don't have to hack the original wiring.
