I still have pins 7,8,9,10,11,12,13,14,15,16 sticking out not soldered to anything on the black HO xj dash harness. And on the grey HO xj dash harness I still have pins 8,11,12,13,14,15,16 to connect. What do I do with These wires? the chart I followed was the HO xj dash to rear renix mj harness, but it doesn't say where to connect these wires?
