Help with 2018 LED Headlights stopped working

I have a 2014 Tundra and I installed 2018 OEM LED headlights using a Morimoto controller and harnesses. Everything worked great for 4 years and now all headlight and DRLs stopped working. I can’t get help from Morimoto to troubleshoot.

I don’t understand how both light go out at same time. All grounds look intact, all fuses good. There appears to be power at the controller input and changes with dimmer.

any help appreciated.

 

Check all related fuses under hood and under dash. Need to test that wiring harness and make sure all wires/pins are getting correct current (and no idea on what is all involved in that).

Suggest you check with @iHacker , can probably help as he builds wiring harnesses to install factory LEDs in trucks that came with halogens. I did the same swap and used the @iHacker harness.

 

I have had issues with morimoto controllers. Your best bet is to install an iHacker harness. No controller and uses hem connectors.
