Front blinker issue 1965 c20
 

I am new to the forum and could use some advice on my front blinker issue.I just swapped out my old column for an ididit tilt column.I also purchased the after market wiring harness kit w/flashers.My issue is the front blinkers come on together right/left but the back works fine and the flahers work fine.Any help would be greatly appreciated.
