Where are the wires for the 91 MR2 for the dome lights?

In the 1991 Toyota MR2, the dome light wires are typically located in the headliner area near the dome light fixture itself. You should find a harness that connects to the dome light, usually comprised of a power wire and a ground wire. If you're troubleshooting or replacing the dome light, access the headliner by gently removing any clips or trim around the light fixture. Always consult a wiring diagram for specific color codes and connections for your model.
