Help! Need help wiring a headlight

The white with black line is ground.
The blue and the violet ones are for high and low beam - in this order or vice versa. IDK

You could test it:
1. Switch on the low beam.
2. If low and high beam both lights up (possibly darker than usual), a bulb's voltage connector is connected to ground. Change the white to another wire.
3. If high beam lights up, switch blue and violet.
4. If low beam lights up, fine.
5. Switch on the high beam.
6. If now both lights up, back to 1. But if only high beam lights up, now everything is fine!
- If nothing lights up, that shouldn't be possible.

SM-G950F ?

 

Caution . . . .

That purple wire is aluminum on the inside.

If you are adding a replacement socket built with copper wire, you are making an aluminum-to-copper splice.

Those are dangerous if not done just right (as a rash of house fires back in the seventies will attest).

The specified copper-to-aluminum splicing materials from Toyota are an uninsulated crimp sleeve, crimped with a controlled-cycle hand tool specifically for those uninsulated sleeves (Elektroingenieur found the one Toyota specifies for a better price as the Lobtex AK15A), with sealant-filled, heat-shrink tubes applied over the top (which Elektroingenieur also found more affordably as TE/Raychem ES1000-NO.1-C1-X-50MM. Didn't find the exact crimp sleeves though; Toyota 82999-52020 is the ticket.
