The flashing red and yellow lights of the Curt Spectrum Trailer Brake Controller # C51170 means you have a short on the blue brake wire. Since you just installed the controller and your 7-way that means it is almost certainly on the trailer side. This is virtually always due to a damaged, frayed, or exposed wire to the trailer brakes so you will need to trace the wires to the brakes and find the one that is injured.
