About the Metra RGML

Buck Pomerantz

New battery terminal accommodates more connections

If you want to add an amplifier to your GM vehicle's system and there's no room at the factory battery terminal for any more connectors, you can replace the long side-mount battery post with this terminal from Metra. This 2-inch long heavy-duty 24-carat gold-plated brass post can be used on either positive or negative battery terminals. Warranty: 1 year.

What's in the box:

  • GM Side-post battery terminal (long version)
  • Nut
  • Lock-washer
