Hi fellow Supra fans.
So I swapped my jspec pre-FL headlight units a few years ago. And the EU-spec lights have got electric motors for the beam adjustment. But as my car originally didn’t come with this option I was missing all the wiring and the adjustment button on the dashboard.
I thought it was a shame to not be able to use this function in the car, so I went along and retrofitted this.
Originally this button will be on the dash if you have this originally. I didn’t have this so bought my own button which you’ll see later.

First of all I cut the original connectors of the head light units.

And replaced them with my own.

Next I ran all the wiring for it as hidden as possible through the fender and through the firewall https://dl.dropboxusercontent.com/u/3472574/BeamAdjustment/IMG_3797 (Medium).JPG

Then had to drill a hole for the button on the dash and fit that with connectors so the panel can stil be easily removed.
Note that i've fitted the red (12V) wire with a fuse connector. I've yet to calculate what would be an appropriate fuse, but for now its an 8A that came with the fuse-holder. I'd recommend putting in something much smaller (like 0,5 or 1 Amp fuse). I'm sure the electric motors don't use alot of power.

This is the result at the head light unit.

Here is a quick clip of the system operated.
This is the schedule I found online, for if anyone else wants a go at it.
For a 12v/GND source I’ve used the 12V input of the dash dimmer switch which is right there in the same dashboard panel anyway.
