I have an 08 CLS550 and I decided to change the horn to the bosches that used to be on like the 1900's SL's, so I just opened the hood and saw the horn, just unlugged the wires and plugged it into the new horn and screwed the new horn in, now i need to put the second horn, Is there like another horn so I can use that wire, if so where is it located, and also if there isn't, is there like a splitter where I can use the two wires and use an adaptor to make it into 4
