I just picked up a 89 s10 with a 350 small block swap and I can not for the life of me figure out what this switch does, and I’m not good at wiring to really trace it. Does anyone know or have an idea of what it could be?

Now first of all, I’m very happy and fortunate that my and the other person involved came out unscathed but, I hate that I lost my baby😭but this is also a lesson that life is to short and be safe out there and trust your gut because I didn’t and hydroplaned into wall and caused someone to run into me spinning out! Be safe out there guys!
