What is your question?
Mercedes S500, Year: 1998 Please help to find where and which relay is for the secondary air injection pump. I have the fuse chart from the original car; but nothing on the relay diagram at all. So many relays in this car, but none of them was identified.

The image I find shows it in the fuse box driver's rear of engine compartment. it is in the row of four relays grouped together on of the middle two, but very hard to identify for sure from my image. There is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subrcription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual try http://www.eautorepair.net/Marketing/Default.asp?VID=125669 and get an online repair manual subscription.
