Plumbing a linelock
Here's mine...
From the rear port of the master cylinder (which is for the front brakes), it goes into the line lock. The output of the line lock goes down to the distribution block for the front brakes. I've got a switch on my dashboard that turns the power on and off for it, and a switch on top of the shifter to lock the front wheels. I've got manual brakes, so what I usually do is pump the brakes two or three times, hold the brake down then press the button to lock the front wheels and do the burnout.
