I currently have a mystery leak as well, but I think mine is internal, may be head gasket related, and it's not solved yet. (Long story.)
Coolant leaks seem to be one of the most frequent problems with the NG900. The best advice I can give you is to search the archives. There are hundreds of posts on this subject, some with really good advice.
Start simple and cheap to rule things out, work up to expensive (head gasket). Any oil in the coolant? Any coolant in the oil? Start it up cold in the morning and watch the tailpipe for a few minutes. Excessive exhaust vapor? Vapor have a sweet smell?
You can rule out the heater core if your splice bypasses it. (Does it?) But if you have never replaced any hoses before, that would be my best guess. Especially since one of them just blew! Tighten down ALL hose clamps. When you can, replace all hoses and use NEW stainless steel clamps. Get a new coolant expansion tank cap, $20 from dealer, cheaper online.
Here is one thread with several good tips.

Good luck. Post back on the board if you solve the problem.
