1. To begin the installation of your new Mustang Hurst Line Lock Installation Kit, remove the negative battery cable from the battery.
2. Find a location to place the Hurst Line Lock Solenoid from the Hurst Line Lock Kit. An easy location is by the master cylinder and distribution block.
3. Use a drill and the 7/32-inch drill bit to drill three holes in the metal.
4. Fasten the solenoid to the Mustang engine bay using the supplied 10mm bolts.
5. Use a 12mm line wrench to disconnect the line off of the bottom rear of the master cylinder.
6. Use a pipe plug from the Line Lock Install Kit and an 11mm wrench to tighten it into the bottom port of the master cylinder.
7. Place one of the 90 degree fittings from the Line Lock Install Kit into the bottom port of the solenoid. Place the other 90 degree fitting in the top port of the master cylinder. Use pipe sealant on the threads before installing. Use a 12mm wrench to tighten the fittings.
8. Use a tubing cutter to cut the line you removed so that it is the correct length to match up with the 90 degree fitting.
9. Use a 3/16-inch by 1/8-inch NPT tubing flare nut from the kit (attached to one of the brake lines) and place it onto the brake line you just cut. This can be cut off using a tube cutter. Use a double flaring tool to flare the end of the line.
10. The line that was removed from the bottom of the Mustang master cylinder should be coming from the driver side front wheel. This line needs to be secured to the bottom front port on the solenoid. Thread the 3/16-inch by 1/8-inch fitting into the 90 degree fitting that is on the bottom port of the solenoid. Use the 12mm line wrench to tighten it.
11. Use a 12mm line wrench to take off the brake line that goes to the rear bottom port on the distribution block.
12. Put sealant on a 3/16-inch by 18-inch NPT male inverted connector from the Mustang line lock and secure it into the left port on the solenoid.
13. Cut the brake line so it can be attached to the left port on the solenoid. Remove another tube flare nut from the brake line in the Install Kit. Place it onto the brake line you removed from the distribution block and cut. Use the double flare tool to flare the line.
14. Attach the flare nut to the connector on the left port of the solenoid. Tighten it with a 12mm line wrench.
15. Take the other half of the brake line that was removed from the distribution block and attach a flare tube nut from the install kit to the end that you cut.
16. Use a double flaring tool to flare the end of the Mustang brake line.
17. Use a tube bender to bend the brake line so that the one end of the brake line will fit into the bottom rear port on the distribution block and the other end will fit into the top front port of the solenoid.
18. Once you have the brake line in the correct shape, attach the brake fittings to the Mustang distribution block and solenoid. Tighten the fittings with a 3/8” line wrench and an 11mm line wrench.
19. Make sure you have the lines in the correct places and they are tight.
20. Now that you've completed installing the portion of the line lock using the Mustang Hurst Line Lock Installation Kit, you need to finish installing the rest of the line lock itself.
