line lock
why is this so hard to figure out? Trace the line down to the dirtrobution block. Once you founf the lie for the front brakes, remove the line from the master cyl to the distro block. Mount the seloniod on the firewall or shock tower. Make a new line from the master cyl to the inlet side of the selonoid. Then make a line that goes from the outlet of the selonoid to the distro block. (Make suure you have enough flex in the line to account for possible body movement) then wire the black wire to the chassis. Run the red wire to your button. On the other side of the button run it to a fuse. From the fuse to a keyed power source. Now bleed the brake system, check for leaks (correct as needed and repete bleeded process)
now after line lock is installed start car, put it in gear (for auto, and manual, but with manual hold in clutch)pump brake pedal 3-5 times while holding pressure on pedal press button. Remove foot from pedal. Car should not move. Mash gas and create lots o' smoke
