The original wiring harness in my 95 SL600 is all cracked. I am going to buy a new but am not sure who I should buy it from. Idid contact www.formercedes.com and they say they make a custom wiring harness that is military spec. They said to call on the phone and talk to Marco. Is this a good source? I may also need new throttle actuators. Is it better to buy new or should I get some refurbished ones?
