why is there two modules?  is one an alarm and the other remote start?  i'm missing two harness can i get them from DEI?  expensive? 

The second part is simply a bank of relays....most other brands build the relays inside the unit.  DEI's method makes mounting the relays a chore, but you can also reconfigure a lot of stuff to make the installation easier.

As for the harnesses you're missing.  Take what you have to the install bay of your local Best Buy or Circuit City-----most installers have all manner of spare parts in their toolboxes.....bring cash.
