The pressure when you apply brakes goes to the front brakes thru one line, the rear brakes thru another. While pushing the brakes you hit the LL switch which locks the pressure into the front brakes ( you actually cut into the front brake line to install the LL solenoid ). Since there is no solenoid cut into the rear lines, the rear brakes release when you let off of the brake pedal.
Its kinda like you pinch the front line while there is pressure in it with a switch.
Its easier to burnout because there is no brake pressure on the rears at all.
Clear as mud?
I don't recall the wiring. I used the Hurst LL with the Hurst install kit and had everything I needed for the job, except the double flare tool. You can bend the lines (SLOWLY) by hand and when you get them like you want them, take the lines to any mechanic and let him flare your ends.
If you really want to hold boost for racing, adjust the rear shoes out tight and have a rough turn cut on them.
