Dome Light Wiring Help Needed (Custom)
Trying to wire in a two foot LED strip to replace my rear dome light and I can't figure out the wiring. I want the light to come on when a door, the hatch, or both are open and to be off when they are not. Took my meter across everything... Still can't figure it out. A Pink, a yellow, and a purple wire come from the factory dome light wiring harness.

After getting these results, I thought Pink and Purple were my hots, and Yellow was my ground. Tried this and with both open it blew the fuse.

using a test light hook the clamp on the pink with the door open then with the other end poke the others un till you get a light that is the ground that will make them come on with the doors and dash

Looking at the diagram for a '97, pink should be battery, the other two are negative's. Yellow should be the switched negative, and black(purple) is the permanent negative for the integral switch.

I thought about doing that, but the only wire that is hot for the hatch open, door open, and both open is hot all the time.. Meaning the light would be on all the time.
