So I bought these off ebay and they seem to be a nice set. The bezels are Toyota parts and while the lamp housings aren't, they do have vents and adj screws and look like they'll fit fine. The switch is the lighted Yaris part and it also looks like a perfect fit. The down side of this kit is that it comes w/o any instructions . I have it mostly figured out with the exception of a "sense " wire that allows the circuit to work (this wire does not supply lamp current). This small wire has to have 12v whenever the low beams are on. It has this connector: Does anyone know where I can plug this in? I suspect it goes under the dash but I'm not sure.. Also, how the heck do I get to the back side of the switches in the dash? Thanks in advance for your assitance!
Your probably gonna need to tap a hot wire at the fuse box under the dash above the brake pedal. Use a multimeter to determine which one is hot with the power on.

Well, that would only give him the ability to turn them on when the parking/headlights are one. He wants them on whenever the car is powered up.
