I took 904's suggestion and used a test light. The 2 purple wires go to the front brake system(double female plug). I installed the WH's disc brakes system which has a single wire, have to figure that end out but still need to connect the two purple wires- probably to my missing dash brake light system. I chased the hanging yellow w black wire to my steering column. Goes to the "left rear". I don't know where that dash wire attaches, possibly a missing "warning light". I have a 1/2" hole above the "HAZARD", and a 5/8" hole below. What switches or lights with wires attach to the holes? Much thanks!
