Will this bolt straight into my car or does it need custom wiring?

This is a direct replacement designed to swap into factory mounting locations. No rewiring—plug and play into your existing harness.

What if one function stops working after install?

Test each function (headlights, turn signal, hazard, wiper) before finalizing installation. If a function doesn't respond, verify the connector is fully seated on the harness.

Do I need any special tools to install this?

Basic hand tools are all you need—typically just a screwdriver to remove the steering column covers and access the old switch. Disconnect the battery before starting.
