Adding Tilt Sensor & Battery Backup to Avital 5305L System

I want to add a 507M tilt sensor and a 520T backup battery to this alarm on a 2001 Camry. It looks like they'll be sharing the same trigger wire on the brain, so it's my understanding each of them will need a diode in line with this wire. Can I get someone with experience to let me know if my following plan here looks good to go? Here's the tilt sensor diagram. Would it just go like: red to #3 on main harness orange to #4 on main harness blue to #10 on aux harness (diode in between and stripe towards alarm brain) The backup battery diagram shows what I think is another diode in line with the brain's constant power wire. If so, I assume the cathode stripe is to be on the side of the alarm? Do these connections for the battery backup seem right? red to car battery positive gray to #3 on main harness (diode in between and stripe towards alarm brain) black to chassis ground blue to #10 on aux harness (diode in between and stripe towards alarm brain)New to alarm installation.

Maybe missing something, I only see the main power plug. If you are hooking up to those, then no is the answer. You should have a couple more plugs on that security system.

I should've posted the diagrams for the other harnesses too. Here they are: You don't think it would be ok to tap into the main harness for power and GWA? I'm thinking I can at least use #10 (blue) on the accessory harness for both of their triggers...New to alarm installation.
