Taylor EST Battery Box Housing Assembly and Cartridge

Does what it's supposed to do. However... this same part on my existing Taylor guitar (approx 15 years old) had a fuse and a screw connector to connect to the earth cable that leads to underneath the bridge, but this replacement part did not have either of those. I soldered the fuse to earth on the circuit board and soldered the earth wire from the guitar to the other end of the fuse. It works, but it wasn't a like-for-like replacement.
