I just want to offer kudos to Eastern Beaver. I ordered and installed the subject item and one splitter with spin-locs. Easily mated up to the ST connector all three switched with ignition. Solid materials and workmanship. The fuse connector, relay, and three connectors all fit in the tool kit cavity with room to spare. The tool kit went under the seat for now. If you ever get in a foul enough mood to throw tools start with them, they won't be missed. I did look at the Thunderbox but it looked a little light for any real amperage and some of the reviews and description sounded like lithium battery voltages might cause it to do more thinking for me than I would like. The moderate wait to get the 3CS HD direct from Japan was well worth it and the quality does not look cobbled up and out of place.
