Trying to install a Continental Radio that looks period appropriate into my 2000 CLK430 with BOSE.

I figured out nearly everything except two things. The radio illumination - I can’t find a PIN that gets power to the radio to illuminate the button lights when the headlights are turned on. How does the factory radio get power for this?

also, anybody have any luck installing an aftermarket radio and maintaining steering wheel control button function?

appreciate any tips.

Quote: Here is a complete and CORRECT list of all wires in the Amplifier plug (see attached pictures too!):



1. BROWN (big wire): Chassis Ground
2. RED with VIOLET strip (big wire): 12 Volt Ignition/Acc
3. BLUE with WHITE strip: Amp Turn-On (Remote)


INPUTS (from Headunit to Amplifier) - 8 THIN wires:

4. GREEN: + Left Front (input)
5. BROWN with GREEN strip: - Left Front (input)

6. ORANGE: + Right Front (input)
7. BROWN with ORANGE strip: - Right Front (input)

8. PINK: + Left Rear (input)
9. BROWN with PINK strip: - Left Rear (input)

10. WHITE: + Right Rear (input)
11. BROWN with WHITE strip: - Right Rear (input)


OUTPUTS (from Amplifier to Speakers) - 10 THICK wires:

12. GREEN: + Left Speaker and Tweeter in the Front side of the door (output)
13. BROWN with GREEN strip: - Left Speaker and Tweeter in the Front side of the door (output)

14. ORANGE: + Right Speaker and Tweeter in the Front side of the door (output)
15. BROWN with ORANGE strip: - Right Speaker and Tweeter in the Front side of the door (output)

16. PINK: + Left Speaker in the Back side of the door (output)
17. BROWN with PINK strip: - Left Speaker in the Back side of the door (output)

18. WHITE: + Right Speaker in the Back side of the door (output)
19. BROWN with WHITE strip: - Right Speaker in the Back side of the door (output)

20. GRAY: + Left Speaker(subwoofer) in the rear deck (output)
21. BROWN with GRAY strip: - Left Speaker(subwoofer) in the rear deck (output)

22. VIOLET: + Right Speaker(subwoofer) in the rear deck (output)
23. BROWN with VIOLET strip: - Right Speaker(subwoofer) in the rear deck (output)




All speakers have two wires: one with a strip (Negative) and one with no strip (Positive):

want the easy way out and not cut wires from the car
metra 70-1784

want the functions of steering wheel with the wire harness crutchfield has the Crux SWRBM-57 Wiring Interface with ISO theres an illumination wire attached on these harnesses
you may not need the crux CS-LOC1 as it might bring down the maximum volume to all the lines but that may depend if you have the bose amp or not.
