Turn signals inop?

Hey guys,
70 cat. turn signals went inop one day. I replaced all the bulbs and replaced the turn signal switch inside the column. Still no luck. No lights, no clicking, no nothing(parts from WCCC). Anything else I can check? The only other thing I can think of is That the wiring on the new part is not correct or not matching up to the stock connector.
Thanks

Thanks I found the issue. It was the fuse on the left side under the dash.
