As suggested, wiring is usually "daisied". Look at the crimp connector closest to the axle / brake that had the problem. Further, if you go back to your 7 pin trailer plug and ohm meter the brake pins (top two away other side from the "notch"), it should read in the 1-2 ohms at best. Still further, also check the grounds to the frame near the brake / axles... maybe you lost the ground. Related to the "missing ground potential", measure the ohms from one pin on the 7 pin trailer connector to a KNOWN ground. Do the same with the other pin. This test will tell you if your ground in the brake system "made it" back to the plug.
