Do these mount at the factory attachment points?

Yes. These bolt directly to the existing Pilot mounting locations — no drilling or modifications needed. You'll be working with the same fastener points the OEM lights use.

Will I need to splice into the factory wiring harness?

These assemblies connect to your vehicle's rear light electrical connectors. Your existing wiring harness plugs directly in — no soldering required on a stock setup.

What's your return window if these don't fit or function as expected?

Contact ModSupply customer service directly with photos and description of the issue. They'll walk you through next steps — most fitment or function issues get resolved quickly.
