Brights are staying on

I have a 2014 SR5. Added OEM 2018+ LED headlights with adapter harness from retrofit. Not sure if its related but the brights stay on. Sometimes they work as they should and other times they stay on. I hit the dimmer switch and sometimes the brights will go off and sometimes they won't but if they do go off, they come right back on and then usually stay on for the remainder of the night. I changed at relays from O'Reillys and that worked for about a week. The ones from the dealer are $75 but I wouldn't think that would have made a difference. Anyone else had this issue? Don't think its the dimmer switch since when I do hit the switch, the indicator light on the dash comes on when it's should and goes off when it should

 

Is "retrofit" a brand? Unlikely anyone here can trouble-shoot this problem for you long distance, except for maybe @iHacker. For a conversion harness that's plug-n-play with zero problems:

Its a brand. Builds a harness similar to iHacker. I tried to order iHackers harness but needed one asap and couldn't get ahold of him in time unfortunately.
