2006 explorer alarm diodes needed?

Hello, I'm about to install a Code Alarm CA 680 into my 06 Ford Explorer. I've been reading about the need for diodes to be installed on the door lock/unlock outputs. This unit has negative outputs for the lock/unlock wire, which I've read to be a direct connect. But i've been doing some reading on this site that says you need to install diodes on the lock/unlock outputs to allow the security module to go to sleep, otherwise I'll get a battery drain problem. I had this unit installed on my 05 F150 and always saw that the battery was draining after sitting for a couple weeks and could never figure out why. Can someone please elaborate on what i need do do? i.e. what diodes do i need to buy, and how do I install them? is it simply inline between the alarm and the vehicle wiring? Thanks!

The BCM goes to sleep NOT the alarm, you need to look at DEI 1076 diagramme, it's here somewhere, problems on the previous vehicle were not alarm related, a correctly wired alarm well add about 30mamps draw to the battery.
