2014 ford focus remote start wiring

I installed a pro start 2 way remote starter on 2014 ford focus and starts vehicle with key in ignition off position. Now I need to install a bypass and not sure which one to use. I am confused as to what the difference is between db-all, db-all2 and db-all2pro. It shows that any of the 3 can be used. I have both keys to program unit and understand I need to buy loader2 to flash proper firmware. I am just wondering which bypass I should order. I assume this car does not have alarm since I locked the door with window down and waited 2 minutes and opened from inside with no issues. Any help would be great, thanks.

First, try pressing factory remote lock TWICE to activate alarm. Then you'll know if there's a factory alarm. Second DB-ALL and DB-ALL2 will both work, forget pro it's for something else entirely.
