I just bought this car and the previous owner pulled this relay to send it back to Japan to get them to send him another one. So, I don't have the original and I don't even know where it goes. What I do know is that it controls the turn signals, hazard warning, heated rear window and wipers.
The MB part # is 1298204926. They want $737 for it. I found it at Auto Parts Warehouse for $435. Fastlane has is for $411. Their part number is : P2039-167642 (I have attached a picture as well.)
If anyone is parting out their car or knows of a yard with one that might have this part, I would greatly appreciate hearing about it. This part is on a number of years of SL500's.
Signalling with my arm for turns is OK when the sun is shining, but will not be very pleasant when it's raining. As I live in Vancouver, it happens to do that fairly often.....
Thanks,
Daryl
