I had one the other day that came back because the rear hatch wouldn't trigger the alarm. The tech sheet says blue at the switch, but for some reason this van would only trigger the other 4 doors on that wire. I ended up hooking the hatch up separately to make it work. I've done dozens of these vans and never noticed it before. I'm doing one today and i'm gonna check this out...
