I'm new to the Mercedes community but I have to say it is turning out to be a fun project. I have a 1974 450 se with a 276 V8 and I have been fixing all kinds of little problems. I am looking for some kind of manual or guide that can help describe the inner workinngs in better detail than the Chilton manual I have been using. Currently I am having trouble getting the brake lights to work. I have removed the circuit board from the taillight assembly and repaired some of the circuits that have been corroded and I still cannot get any lights. I have been trying to locate the brake light switch on the brake pedal but so far I can't figure out where it is. All I see is a boot surrounding the whole assembly but no wires coming out of it. If anyone has any information or is interested in taking over my project I would appreciate your response. This car is straight and fully intact with 69,000 miles. Thank you, Ryan
