Glad it arrived safely wouldnt have been the first part for aus post to lose. Let us all know how you go installing it.  My advice would be remove either the 10 or 1000 points reel and put the new reel in its place then one at a time unsolder and transfer the wires from the original to the new from top to bottom or vice versa that way a quick look and you will know you put it in the right spot
