Will this plug directly into my truck's wiring without modification?

Yes — the connector matches factory OEM harnesses for these trucks. Plug and play, no rewiring required.

Does the switch handle both turn signals and hazards?

Correct. This switch covers turn signal operation and hazard function. All lever positions are included.

What if the steering column wiring has corrosion or damage?

Test the existing harness before installing the new switch. If wiring is compromised, have it cleaned or replaced — the switch itself can't compensate for damaged vehicle wiring.
