Radio Adapter Harness - MR2

The Metra Radio Wiring Harness For Toyota MR2's allows for the installation of an aftermarket radio using the existing factory wiring and connectors. The 1991 MR2 with premium sound is the only harness that does not exist due to it being a one-year only radio connector. 

  • Toyota MR2 1985-1995 WITHOUT premium sound (One 10-pin plug and one 6-pin plug)
  • Toyota MR2 1992-1995 WITH premium sound (One plug and two pairs RCA connectors to utilize factory amplifiers)
