Friends, tell me, where are the brake circuit connection contacts under the hood? I have two lights off on my dashboard.

Check the bulbs first.

On my 74 SS1, the lights are connected to pressure switches on the ACVs just above the accumulators. (pic 1)

On my 74 SS1 the left hand heater switch marked "upper" switches the compressor on and off. Top and any position to the right is off, any position to the left is on. (pic 2)

I think your 71 SS1 will be the same.

Do those lights come on when you turn on the ignition? They warn you of low or no brake pressure. There is a button to push on the dash to test the bulbs. If they don't ever come on don't drive the car until you have fixed them. I have had Shadows come into my shop with the bulbs in those warning lights removed to hide brake pressure failures, very dangerous. The other way to check the bulbs in those is to shift the transmission into R (reverse) and turn the ignition key to start. The engine will not start but those lights should light up.
