On my 79 the brake wear light is on. I have verified that all four sensors are good, and cleaned the connections where the sensors plug in.
Unlike my S4, there is not another connector on the shock towers (front) or in the tire well (rears).
Does anyone know if there is another spot I should check?

I found the bad circuit by checking the at the CE panel. On my 79, Q7 and Q8 are the front left circuit, U5-U8 are both rear circuits, and K6 runs to one side of the front right.
If q7 -q8 has no continuity the problem is with the front left.
If U5-U8, then the rear circuit is bad.
If both of the above is good, the the front right is bad.
If the rears are bad (like mine) the circuit runs from CE U8 to one side of the right connector, the other side of the connector runs to the left connector, then the other left connector runs back to U5.
