Looking to add interior lights that come on when the park lights do on a 2017 ram 2500. Where is the best place to tie in? I looked at the relays but was not able to determine which one controls the interior lights. I read a post where a guy found a plug in the harness but no photos of where to find it.

Sorry, can't help you, but I am curious as to why you want the interior lights to come on with the park lights? Isn't there a switch on the dash or on the interior lights to turn them on when you need them?

The parking light was an easy way to describe it, just looking for a couple small lights that come on when I turn the exterior lights on. I have had lights like this for years and just tied in to a fuse block at the park light fuse but everything is now on relays. I looked in the fuse box and pulled every relay and the lights still came on so not sure where it is.

I added a switch with a small blue led for my sub amp, so i can run subs when I want/ turn the off when I don't. It's just the right amount of light and the right kind to be sufficient but not too bright or annoying or distracting while driving.
