Question about 2003 Toyota Corolla
I am installing an aftermarket 02 sensor. Wiring color codes are different than my OE sensor.
My OE wiring has 2 Black wires, 1 Blue wire and 1 White wire.
Iknowthe2 Black wires are the Heater wires. I need to know whichistheSignalwire and which is the Ground wire on a 2003 Corolla.
I know which wires are which on the new aftermarket sensor so that is not an issue.

Open the back trunk, look near the top of the trunk, and pull the two black levers. They have a seat folding down symbol. That will release the locks to fold the back seat down.
