Steering Column Replacement???

[Charles2501]

I am swapping out my old steering column on my 71 C10 Automatic for a used one I picked up. However the used column has a different a flat harness and the original one has a semi circle harness for the turn signals. I looked on LMC and they only show one which is the semi circle except for the replacement columns which so the flat harness. Can someone educate me on these different harnesses and can I swap the harness out and be good with the used column I picked up.
