Need help

2018 Tundra. I have amber and white led lighting for undercarriage. But both share common ground. I would like to connect the white to interior with key activation, and the amber to running lights with turn signal activation. Because switching is done on negative side, i cant see how to make both work independantly. Any ideas? Which wires can I connect to?

 

Welcome from NC! Wish I could help but I am sure someone with experience or knowledge with this will chime in.

 

That didn't work on my 2017 I had to grab it from behind the dash which its not hard to do..

 

I can get into the courtesy circuit in several places. That not the probem. My issue is that both led colors share the same ground. This led strip should have separate ground wires for each color. Any help for that? Thanks

 

If you know of a + that gets powered when ever you like. Then My only suggestion would be to use a relay on the second ground..
