Wiring steering column

[flattie39]

I'm in the process of rewiring my 69 C10 Stepper and have got to my newly rebuilt tilt steering column (replacement for the original straight one). The curved female connector on the column has the normal wires (Blk-Lt Blu-D Blu-Brn-Purp-Yell-Grn-Wht). The male connector coming off the wire harness is the same except there are 2 Lt Blu and 2 D Blu wires together instead of just one like the other pins. One Lt Blu is front left turn and one D Blu is front rt turn. Where do the 2nd 2 wires go(or come from)? Thanks,
Ken (aka Flattie39)
