Line lock question-which line goes to front brakes
 

I'm installing my line lock while the engine is out and I need to know which line coming off of the silver valve (the one that comes from the master cylnder and is mounted on the strut tower) is going to the front brakes. I assume that the front line goes to the front brakes but I'm not 100% positive.
Thanks

I just found out that the line going from the back of the master goes to the front brakes. So I was wrong and the line that is closest to the firewall is the line that feeds the front brakes.
