After years I'm finally reinstalling brake system. I have the power brake booster. The junction block that is attached to the frame at the bottom of the steering column appears to be properly attached to the frame and has 4 openings. One appears to go to the booster. The connecting nut at the junction block appears to be 10 mm and threads into the junction block easily. Is this right? Everything else is 3/8". Another brakeline out of the junction block goes to another junction block on under left fender which feeds left front brake and right front brake. A third brake line out of the junction block feeds rear brake junction block. Which brings me to the fourth opening. If I've connected the first three correctly, this opening is on top facing you as you look down. I've seen diagrams that the brake light switch goes here, but this opening is shallow, as if it was meant to accept another brake line or similar fitting, The brake light switch doesn't want to thread easily and appears to be designed to screw in deeper than the opening permits. Is there a fitting (that doesn't show up in any manual or parts catalog) that screws into the junction block and will accept the switch? I've seen a diagram that shows the brakelight switch installed on the booster brake. And I've seen the switch light installed on the master cylinder. Both of these last two options seem to require a special bolt that accepts the switch and allows fluid to flow. And if the switch goes in another location, how do i plug the fourth opening in the junction block?? HELP!
