Hello guys, so I decided to replace the brake lines for my 2010 G37X sedan. I replace the rear no problem. But when I got to the front I notice that there was multiple brake lines. But in the package there is only 1 line for each side R and L.
How do I install these lines, please help me!!!!!!

Please show me pictures if anyone has them.
P.S these are regular Oem brakes.

Thank you
