DJT88 Posted April 9, 2015 Share Posted April 9, 2015 (edited) 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. https://dl.dropboxusercontent.com/u/3472574/BeamAdjustment/%24_57 (1).JPG First of all I cut the original connectors of the head light units. https://dl.dropboxusercontent.com/u/3472574/BeamAdjustment/IMG_3794 (Medium).JPG And replaced them with my own. https://dl.dropboxusercontent.com/u/3472574/BeamAdjustment/IMG_3795 (Medium).JPG 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 https://dl.dropboxusercontent.com/u/3472574/BeamAdjustment/IMG_3799 (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. https://dl.dropboxusercontent.com/u/3472574/BeamAdjustment/IMG_3801 (Medium).JPG https://dl.dropboxusercontent.com/u/3472574/BeamAdjustment/IMG_3802 (Medium).JPG https://dl.dropboxusercontent.com/u/3472574/BeamAdjustment/IMG_3803 (Medium).JPG This is the result at the head light unit. https://dl.dropboxusercontent.com/u/3472574/BeamAdjustment/IMG_3806 (Medium).JPG 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.

DJT88 Posted April 10, 2015 Author Share Posted April 10, 2015 Thanks guys! just thought I'd document this as it might be something worth doing when you've changed from headlights without this option to ones that do. Quote Link to comment Share on other sites More sharing options...

HI, Don't happen to have those pictures available to upload? Quite fancy doing this myself. Cheers Quote Link to comment Share on other sites More sharing options...
Silber Supra 97 Posted March 27, 2021 Share Posted March 27, 2021 Very informative post. I have had to do the same with my US Spec after importing to Europe. I used all original connectors from Toyota, new pins and original wiring colors as original and made my own entire wiring harness. Quote Link to comment Share on other sites More sharing options...
