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.

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...
