These markings are check aids only; do not use them as a substitute for verifying the relay number, pin layout and circuit position.","[INSTALLATION TIPS] Disconnect battery power before service. Pull the old relay straight out, avoid hard prying against the fuse box, and inspect the socket for heat damage, corrosion, moisture or loose terminals. Do not install if the original relay uses a different pin count, different 87/87a arrangement or different relay shape.","[2-PACK SERVICE VALUE] Includes 2 relays for keeping one spare or replacing two matching relay positions after diagnosis. May help restore circuit operation only when the original relay is confirmed failed, damaged, overheated, corroded or missing. This listing does not guarantee repair of unrelated wiring, fuse, module or motor faults.","[IMPORTANT COMPATIBILITY NOTE] Not a universal relay. Do not buy by vehicle model alone. Match OE number 13509878, 12V rating, 5-blade terminal pattern, 85/86/30/87/87a circuit diagram and the fuse-box position. If your original relay is 4-pin or has a different 5-pin layout, choose the correct relay instead.","[TRADEMARK / FITMENT NOTE] Vehicle names and part numbers are used only to help verify compatibility. This replacement relay should be selected by original relay number, fuse-box diagram, terminal layout and vehicle manual, not by appearance alone."]
