The Grey is the Backup light. The Blue changes to White after one of the wiring harness plugs so if you can't find Blue look for White. one more thing, F12 = Runniging lights, F15 = Brake lights F2 & F25 are the Turn Signal fuses in addition to the constant 12V fuse F18. Any of these fuses could cause things to not work. F18 is used to power the Mercedes isolation circuit to run the trailer lights. I don't think you need this if you are using a non isolated after market trailer lighting adaptor.
