Non-intrusive auxiliary interface. Advice/info wanted!

For a 2012 Tacoma DCSB TRD.

OK Tacoma World Gurus,

I am starting to plan my accessory electrical interface setup and am in need of information and advice.
The plan revolves around a desire to leave the stock harness intact without one single tap.
Circuit breakers and a Blue Sea PN 5026 or two and relays will be at the core.
The information I am looking for is the type/style and source of connectors for the following systems:

1. Tail light/reverse lights. Purpose: To trigger relay for supplemental reverse lights.


2 .Fog lights. Purpose: Not sure yet. Possible sync with aux. lighting.


3. Right side power door lock if there is a sub connector (a main harness plug would negate this idea). Purpose: For power tailgate lock.


4. A great place to connect a switched 12v connection (again, using plug interface). Purpose: Trigger relays for multiple accessories.


I am figuring that I will end up having to source most or all of these connectors at wrecking yards and will need both male and female connectors to create the interfaces.
The final goal of the wiring is to handle multiple auxiliary systems with an interface that requires no modification or intrusive tapping of the factory wiring.
Feel free to give any advice, comments, and ideas to this thread!

 

No one?

Blue Sea fuse block is on the way.
I have a circut breaker block 60a, 60a, 30a, 30a that I had intended to use but I think the 60amp coverage will not be suitable for a 12 position fuse block. It will take up a lot of space too.
Any input?
Plan is to run:
OBA.
Lighting; front, rear, sides, rock and supplemental reverse.
USB charging in cab (Blue Sea).
In cab inverter.
HAM.
OB Hot water (maybe).
And more. Leaving room for the unknown.
