The relays can be bought on line or any truck dealership should stock them. Also try FleetPride or any large truck part supplier or even auto parts stores. Check pricing if you use a dealership, they like to soak us on these little items. A .10 fuse will sell for $50 at the dealership, when you can get a dozen of the same fuse at Napa for $5.
