Replaced factory cluster w aftermarket. Turn signal issues

Is the headlamp switch grounded?
That’s a good question. I didn’t change any of the wiring there but I should have mentioned the whole original cluster has been replaced with a plastic insert. So perhaps the grounding issues could be there? Classic dash supplies a grounding ring. They only sent one though. Currently I have it on the wiper switch. I could switch it to the headlight switch side and see if that helps?
