i have a 89 std civic with a b16a2 swap in it.. but i cant seem to figure out this electrical.. somthing grounded out inside the cars interior harness.. and sometimes the lights and everything work.. and then i will go to flip on the lights and then car dies.. the motor harness and ecu is not in car and neither is the dash harness.. i cant find out why this keeps doing this.. i been working on it for over two weeks.. and trace the wires then i think i fix it and its somthing else.. any ideas??
