i had to replace the rearend in a 89 suburban and i cant figure out how to get the park brake lines back together?

does anyone have a diagram or a walkthrough on how to get them back together?

A service manual is what you need. Depending on where you live, library's have service manuals. Are you needing to know how the emergency brake cables hook into a drum brakes? Or are you swapping a disc brake rear axle in place of a drum brake rear axle? If none of the above. Plain emergency brake cables should have an end on each cable coming from R/H & L/H drums. These ends fit into a clip that connects the cable coming from the emergency brake pedel back too the rear end cables. When you took this apart, it's basically a reverse assemble kind of procedure.
