The car is not yet running but I am trying to piece together all of the random wiring that the previous owner did. It kind of looks like they hardwired the fans to run 24/7 when the car is on? It is worth mentioning the car is a 92’ but didn’t come with any sensors in the bottom of the radiator so that might have something to do with this wiring job. I can say that the passenger fan turns on when the key is in the ignition but I’m not done wiring the starter so i don’t know how it’ll act when running. shouldn’t one turn on once it hits a certain temp? Also what is the 4 pin plug for? I haven’t found anything near it to plug into. (radiator sensor that i’m missing?) Thanks in advance, let me know if i need to add more info.
