Replaced factory cluster w aftermarket. Turn signal issues

I looked again and I think you’re right. The path of the black wire traces over to where the brake warning light is. Next is gray witch traces to the oil pressure warning light. And next to that is the blue with white tracer that also goes to those two as well as a path to the voltage limiter on the right. The blue/white is switched 12v and I used that as the power wire for all the new cluster. Looks like I’ll be ok with the black wire not being hooked to anything, I just wont run a brake warning light.

Thanks for clearing that up.
