The Metra Radio Wiring Harness For Toyota MR2's allows for the installation of an aftermarket radio using the existing factory wiring and connectors.
NOTE: The 1990-1991 MR2 with premium sound 14 pin connector is the only harness that does not exist due to it being a one-year only radio connector. You will have to make something custom or rewire your system
Fitment:
Toyota MR2 1985-1999 WITHOUT premium sound (One 10-pin plug and one 6-pin plug)
Toyota MR2 1992-1999 WITH premium sound (One plug and two pairs RCA connectors to utilize factory amplifiers)
