After 30 minutes I think I was able to attach a pic.
I originally posted this because I thought it would be fun to hypothesize on what it could be before I looked.
After looking, I still have no idea.
The arrows point to where these lines should be connected. They are a pair black metal lines that run along the length of the passenger side. The pic is me under the side looking towards the rear of the vehicle.
The fluid was a real green, almost neon, color and it did smell like gear oil.
