A little bit of a wiring diagram would have been helpful here. I don't have the door sills yet is there 3 wires coming off of them? You said you ran a ground but it looks like your running in series with the wire you pulled from the harness?
I unfortunately didn't have a wiring diagram as this was my first video and didn't really think about that at the time. I did get my info from a other video which I believe I mention where I got it from but yea sorry about not all the info haha I tried to be as detailed as I could
To be honest I'll have to rewatch this to jump my memory on why I did the negative as I don't remember haha. I'll get back to you but I believe it's just two wires
