So you've got a Pioneer MVH-S21BT (or MVHS21BT) but the wiring harness is missing or damaged?

No problem—this is the replacement you need.

It's a brand new, unbranded wire harness that plugs right into the back of that specific Pioneer model.

Whether you're installing it in a new vehicle or just lost the original during a project, this harness gets you hooked up.

It's a simple, no-frills part—just the wires and the connector.

No UPC, no MPN, just the harness itself.

If you're handy with a crimper or solder iron, you'll have this wired up in no time.

Grab this, match the wires to your car's speaker and power leads, and you're back in business.
