Default trailer wiring w/module: 12v or not?


I was looking at posts about the trailer wiring. I see that some run a 12v assisted module. this Module would have 6 wires coming IN(one is 12V) and goes out to a 4 pin trailer connector.

no 12V:

I've found 2 kinds of boosters/modules, some have a 12v source and wires for lights. Some have no 12v and only 5 wires into a 4 pin connector.

Question is:

Can the stock wiring handle 2 more lights from a trailer? do you need the 12V assisted module?

I looked at the wiring diagram for the WRX wagons, I do see the 6pin connector that comes stock on it. I can't remember if this 12v in the 6 pin is seperate from the other wires in the OEM rear harness and has its own fuse(I don't think it does)

if there is no seperate 12v wiring with fuse for the Wagon trailer harness, that means that we can tap the wires at the light and take the power from the tailights.

Of course the added 12v won't hurt, but it seems to me that it's not needed.

Can someone pls confirm or deny this?
(I can't see the rear tails/wiring harness diagram right now)
