It depends on what changes you need to do. A general answer could be
"Open html-mod.el and change it", but I won't be that mean... :) Some
people just want to change the "syntax hilighting" (font lock in Emacs
lingua), some want to change the behavior of some function. Maybe if
you describe in more detail what you want to change, people can make
suggestions?

This is how I add the sql, ins, cre and upg file extensions to use
sql-mode:

(setq auto-mode-alist 
 (cons '("\\.\\(sql\\|ins\\|cre\\|upg\\)$" . sql-mode) auto-mode-alist))
