Added 18 lights with harness now i have an issue.

This is the first thing I thought when reading thread title.
I just clicked to see where the hell he put 18 lights.

 

Yes, all interior lighting was back to normal.

 

I’m reviving this thread because the same thing just happened to me! I have a 2017 tundra and upgraded to oem pro LED’s and installed using the aftermarket harness, the drl harness, and swapped the pins around. However, I did not do the DRL delete because I kind of liked the way the amber lights stayed on in the day time. Everything worked fine for a month, and just today I realized my console lights flash when the blinker is on. The console lights only flash when the blinker is on and the headlights are off. If the headlights are on and the turn signal is on, then the console lights will not flash.

Anyways, I’m going to try to do the DRL delete and see if that solves the problem. Fingers crossed.
