Will this plug directly into my vehicle's existing mirror connector?

Yes—this is the factory OEM unit with original Mazda connectors. It will mate with your car's factory harness without adapters or modifications.

Do I need to reprogram the blind-spot detection after installation?

No reprogramming required. The BSD signal integrates with your vehicle's existing system immediately upon connection. If your car came with BSD from the factory, this mirror will work with it out of the box.

What if the power fold or heating element isn't working after I install it?

Test all functions before finalizing installation—power fold, heat, and signal operation. If any function fails at that point, return the mirror within our standard window. Once fully integrated into your wiring, troubleshooting becomes a vehicle electrical issue rather than a mirror defect.
