Replaced factory cluster w aftermarket. Turn signal issues

the (+) to your warning LED will need to come from switched 12 V , the blue with white. This black goes to (-) side of the LED. The rest of factory wiring going to those 2 switches that complete the ground should still be there.

I have the blue/white wired to the switched 12 v from the new harness. It does have a provision for park brake light (2 separate ones it seems here, pink and tan.) As long as one of those is switched 12 v I assume I could use that for the + side of the LED and I will hook the - side of the LED to the factory black wire that ran to the old cluster. The factory wiring on the other end of that circuit should be unchanged as you mentioned at the other two locations.
