Here is how I'd approach the problem.  Disconnect the starting battery and
get it fully charged.  Disconnect the aux battery (charge it while
troubleshooting the rest).  Reconnect the starting battery while using an
amp meter (set it up to the highest range to start with) to check for
current draw.  If anything more than 50 to 100 ma with everything off start
disconnecting the new things you connected during the aux install, one at a
time (or disconnect all and start reconnecting one at a time).  You should
be able to track down the offending circuit or component that way.
