We updated our 1965 Mustang with front disk brakes. We installed a new distribution block that has connections for brake system warning indicator (like later classics). Does anyone have a diagram on how to connect it up? :?:

The connector has 2 prongs. See the attached picture. Thanks.

It just acts like a switch, when there is a leak in one axle, the plunger moves to one side and closes the switch. You would run one side of the switch to a fuse to the ignition side of the ignition switch, the other side of the switch would go to a 12 lamp assembly, with the other lead of the lamp to ground. You will have to improvise a indicator light, since the 65 did not have a brake malfunction indicator. I consider the tandum master cylinder to be the best upgrade to my 65. Good Luck

Some of the problems with the switch are in getting the plunger centered so the light is out, (if its not stuck), it is easiest with 2 people, one person presses hard on the brake pedal and watches the light (the ignition key will have to be on so your indicator light can work), the other barely opens a brake bleeder valve on either a front or rear brake, its 50/50 whether you guess right to start, while you are letting brake fluid out, the person in the car needs to tell you when the light goes out, immediately close the bleeder valve, if it didn't go out, then do a bleeder on the the opposite end of the car. IF you bleed the fluid too fast the plunger can go past the centering point causing a blink in the light, and it will be at the other end of travel. If you do both front and back and it will not go out, then it is stuck, inside. Post your results. Good Luck.

The Distribution block that Ford started using in 67 (As you have), has a grounding switch to light the bulb incase of a imbalance in the Dual Braking system.

Your 65 does not have a light, so first thing, find a 12V light in the fashion you desire, mount to a position you will see.

Run the positive (Using a fuse of course) to a source.

Next, run the negative to the Switch on the block, when shuttle moves, light will eluminate.

Oh Yes, you see two prongs on switch, it means nothing, both are bridged--Look into the hole, or use a tester.
