Good To Know

Q: How do I know this relay fits my truck? A: Confirm your existing relay carries the 15016745 number or that your application lists that number. Match the terminal count and pin layout before ordering.

Q: Can I replace just one relay? A: Yes, relays are typically replaced individually at the failed position. If several circuits share the same part number, inspect the others while you are in the fuse box.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
