I feel your pain! I blew the fuses on both power ports on 2015 E450 (slow learner so I plugged the same bad component into two different ports). It took me a bit to locate the which fuses I had taken out. They were in a big box of fuses under the hood and they were not the usual automotive fuses but were $5 low profile J case fuses.
