88 brake proportional valve hookup and bleeding

[Rodehazrd]

my truck had no rear brakes on ice I had to take out of gear to stop . I replaced the two lines from the front and the proportional valve. now I have to really pump up the brakes to stop, I fear I crossed some lines. anyone have a drawing of how the valve lines hookup? The valve is a Mitsubishi L200 model with three ports it has a bleeder but I never got much out of it. right rear bleeder has flow as do both front bleeders.
Any help is greatly appreciated

I found my issue. the line to the front was crossed with the line from rear master. I replaced the lines and got them crossed. one thing put me onto the solution, I could see fluid boil in the master when the brake was pumped several times. not the first pump but after several.
