I need a diagram of a dodge neon brake lines, do the rear lines split in the middle or do they run all rhe way back seperatly? Thanks

They are separate.
Go to this web site for excellent instructions on how to change them. There are many illustrations. http://forums.neons.org/viewtopic.php?f=1&t=337657
There are also factory pre-made lines from the dealer for $20 for the pair. They were part of a recall and the cost is very low. I just installed them. Get the part numbers at the web site above.

The lines should run down the drivers side along the frame. There should be three.Two larger lines are the fuel delivery and the fuel return. The smaller single line is your brake line. It will connect to a splitter on the rear axle housing and then go to each rear wheel.
