The cruise control wasn't working on the beater (1983 240D). So I did the check on the cc switch - all good, so I then did the ol' standard resoldering the cruise control amp connections and whoopee! it worked!

But my excitement was short lived. It stopped working until I turned the car off and started up again.

I later discovered that it is only when I pushed the brake to disengage the CC that it wouldn't reengage.

I checked the connections to the brake pedal switch. The switch is fine - closes when the brake is actuated (as the Krauts put it in the manual).

However, the wiring in the manuals doesn't match the wiring in my car, so I don't know what the deal is. But none of the wiring seems to match, yet it works fine, so I think I must have some different wiring becuase it was a later model and they changed the wiring but didn't change the diagrams.

Anyway, mine looks like this - 4 wires (2 green, 2 black I think) come down to the brake pedal. One goes to one pin of the connector, the other 3 go to another connector and are basically all connected together and back to the other pin of the connector that goes on the brake switch.

Basically, I don't think the wiring at the brake pedal is right. Any ideas about how it should be? Anyone feel like getting under the steering wheel and seeing what there brake pedal wiring looks like? Or maybe you've had the same problem and fixed? Calling all gurus....

Before you ask, yes, the brake lights work and the ground is good! I checked that one.

Thanks!
