I must ask because it doesn't make any sense to me, Why would you want or need to control the rear brakes during a burnout? Don't you control wheel speed with the long pedal on the right?
I think you may be misunderstanding. When you put the line lock in the rear line, you turn it around, so when the solenoid is activated, it simply blocks pressure from the rear brakes. It acts the same as plumbing the solenoid in the front. The only difference is it's your foot controlling when and how much the front brakes are applied vs your thumb on a switch during a burnout. And yes, your right foot still controls wheel speed.
