Hi, I am going to add a toggle switch to my radiator fan from the battery. My question is, can I leave the original climate control relay switch (ccrm) connected to the radiator fan?
whould there be an issue with current going toward the ccrm? I will be splicing next to the plug of the radiator fan. I dont want to cut the fan wires off the cars system.
