Previous owner of my 2010 4Runner replaced rear brake lines starting from the connector on the driver's side. I am in the process of replacing front and rear brake lines and hoses and want to make sure that everything was done properly. According to this diagram, there are 4 lines that run from master cylinder.

1 - Rear Passenger's Side
2 - Front Passenger's Side
3 - Front's Driver's Side
4 - Rear Driver's Side

Lines 1 and 4 pass through a connector that is located on the driver's side frame.

One million dollar question. Which line is the upper one on this connector and which line is the lower one?

As you can see in the image, the previous owner cut OE lines and routed new ones around the fuel tank.

I am not sure if it will make much difference, but I don't want to connect the lines the other way around.

I just replaced all of those lines on our '10. I used oem lines from Toyota. I am guessing that the old owner did not want to mess with removing the fuel tank etc. to use them. The #47324 (lower one) should be going to the right rear if I remember correctly?
 
Had to figure this out the hard way. I put stickers along one of the lines and traced it all the way to the top.

The upper one on the connector is line #1 on the master cylinder, which is rear passenger's side. It is marked with green at several locations.

This means that the lower one on the connector is #4, which is rear driver's side. It is marked with pink.
