😱 👨🚒🔥🧯... I would use a fuse, or a add on fuse tap, and relay if needed, probably not in this case... This is how wires can get hot and can cause a fire if there ever a short or something, I've seen stuff like this happen... Remember a friend of mine's car caught fire way back in high school days, because of his install of a custom car stereo. I've done a lot of automotive custom wiring over the years, and remembering this happening in high school has kept me doing stuff the safeway always.
