Turn signal wire harness?

My son had a blow out and part of the tire ripped through the front passenger side headlight. It tore through the wire that went to the blinker. I replaced the headlights, but I cannot seem to find the harness piece that goes to the blinker bulb. I have the wires capped off at the moment.

Headlights work. Brakes work. Driver's side blinkers work. The passenger side obviously has an issue, but the running lights and dashboard lights are out. Is this all tied to that harness piece that I need?

All fuses are good. What would the name of this piece be and where might I be able to find it? AutoZone does not offer it and was not too helpful when asking. Think he was having a bad day. Told me turn signal harness.

Any help would be appreciated. Just trying to get him up and running again where I do not have to worry about it getting dark and him being out there with no running lights.
