Hi guys, I am trying to install the 2017+ JDM DRL, but from what I am aware the USDM BRZ does not have the proper harness.

My plan is to create a Y-harness (1x8pin[headlight] + 1x4pin[DRL] -> 8pin[headlight]).

I purchased the following connectors off Aliexpress (b/c Toyota wanted $40CAD per wire . . . )
- 8pin - 90980–10896/90980–10897
- 4pin - 90980–11027/ 90980–11028
--They come with the connector, pins and seals.

I have two questions that I am trying to figure out:

1. There are 2 ground pins (or 3, trying to figure out what the last pin is for)
Which do I tap into? (I assume that one is for low beam, one for high beam and one for everything else)

2. Does anyone know what gauge wire is used for the headlights? There is one thick wire and 6 others are the same.
According to the wiring pdf the part (82998–12430) - wire outside diameter is 2.6mm and nominal size is 2.00

The pinout is (driver side)
[Low-Beams | Ground | High-Beams | X ]
[DRL |Turns | unknown | Ground ]

Thanks!
