Hello! Amazing work.
Upgraded/Replaced my 2015 Halogens to 2018+ LED Headlights. You can find them on eBay or Yahoo auctions typically close/around ~$2K.
I used the OEM LED Headlight retrofit/wire harness guide by joey to guide me in the right direction in making a conversion harness.
I’ve read various/conflicting info regarding how to wire up the newer headlights, the pin out, differing wiring color schemes between models, etc. so I found that the best way was to figure out the new headlight pin out on my own. I did not wire up the Self-Leveling module (yet) as my stock halogens/chassis wire harness did not have them.

Note: If you de/re-pin the stock chassis harness plugs into connector 90980-10897, you won’t need the stock 5-Pin & 6-Pin connectors (90980-11598 & 90980-11193). You can buy most of the plugs on amazon or the Toyota dealer.

There are 7 solid colors (White, Green, Blue, Grey, Yellow, Black, Red) on the main 8-Pin plug on the 2018+ headlights. I started by making an 8-Pin pigtail harness using Female Connector Part #90980-10897. I assumed white & black were ground, then using a voltmeter to verify most of the pin out, then using a 9V battery to see what powered on. If anyone gets a pair, make sure you verify your own pin out (may vary) by using a voltmeter and testing it on your own.
The headlights I purchased did not have the turn signal indicator bulb/socket. The old halogen ones do not fit, so I modified them to work by using a razor blade to trim the socket plug tabs. They fit well, no problems so I did not bother to find the appropriate bulb socket/plug part # for the newer headlights
I took my front bumper off, mounted the new headlights, double checked its function by using the pigtail to plug in the wiring one by one to the stock harness, then measuring & cutting to length, then proceed to crimping on the terminals and placing them in the appropriate parts of the connectors. I haven’t figured out what Grey Pin #4 was for, but my Lo/Hi, DRL, Parking lights all work well without throwing a check headlight sensor indicator.
I’m curious. Are you selling any pair of headlights pre wired with the correct harnes
