I been looking on the net trying to see if I could find anything on the TCH & some wiring diagrams so I could maybe use the factory wiring instead of adding another switch to the car.
I'm not even such if the car has the wiring already there or not.

The factory fog lights use a switch in the headlight stalk. The TCH does not have this switch nor the wiring for thwe fog lights in the steering column.

There was a person on greenhybrid that added the XLE headlight switch and ran some wires from it to the fog lights he installed. he said the hardest part was keeping a switch inside the steering wheel in its correct position. He had to have it re-initialized by the dealer since it fell out of the correct position.

:eek::eek::confused:
