The blue/white is probably the cold start/choke warning light - goes to a switch built into the original choke cable with a black wire to earth. Could the other one be the brake fluid pressure differential switch wire? Would normally go to a switch in a block with the two brake circuit pipes going through it and indicate a failure of one brake circuit.
