Direct-Fit Radio Harness for GM Vehicles

This METRA 71-2105 wiring harness plugs directly into the OEM radio connector on compatible General Motors vehicles from 2006 onward. It carries power and four speaker channels through one 16-pin plug and one 14-pin plug. The design restores the factory wiring interface when installing an aftermarket head unit.

Installers Replacing or Repairing Factory Radio

Technicians and DIY owners who need to connect a new stereo without cutting the vehicle harness will find this plug-and-play solution suitable. It also serves to repair a damaged original harness where the plugs have been cut off. Vehicles outside the listed Buick, Cadillac, Chevrolet, GMC, Hummer, Pontiac, Saturn and Suzuki applications or model years before 2006 cannot use this harness.

Dual-Plug Connector Configuration (16-Pin + 14-Pin)

The harness terminates in two distinct connectors: one 16-pin and one 14-pin. This specific pin-out matches the factory radio socket on the supported Impala, Monte Carlo, Silverado, Escalade and related models. Verifying that the vehicle presents both connectors is the single specification that confirms correct fitment.

Questions about this item

Will the 16-pin and 14-pin connectors need replacement if the locking tabs break?

The harness uses one 16-pin plug and one 14-pin plug that mate with the factory radio; if a tab breaks the entire harness must be replaced because the connectors are not sold separately.

What is the first limit reached when the harness carries power and four speaker channels continuously?

The factory wiring and connector pins set the current limit; sustained high-volume output can heat the pins before the harness itself fails.

Does the harness generate any heat or noise when the radio runs all day?

The harness is a passive wiring assembly with no active components, so it produces no noise and negligible heat under normal radio operation.
