You could be in for a bit of digging here!
First thing I would say is that the two scripts have a name clash. The scripts try to keep all their variables private by encapsulating the code within an immediate function.
So, at the top of teh script you have…
var gauges = (function () {
In you second script change that to…
var gauges2 = (function () {
Another problem, the script uses jQuery to perform the AJAX queries. It assumes it has sole access, so the two scripts will interfere with each other - e.g. line 2616…
if ($.active > 0)
$.active will be greater than zero if the “other” script is currently running a query. 
Horrible hack - just comment out the following _jqXHR.abort(); command!
With those two changes the gauges function - how reliably though…
