The OEM Horn Relay has long been discontinued but this new aftermarket relay will work perfectly. Replaces the relay on 1958-8007 FJ25/40/55 models. Note: 1970 to 80 models replace your OEM plug with spade terminals. 1968 and earlier models had screw terminals on relay. Simply replace your screw terminals with spade terminals. UPGRADE: 1981-83 FJ40 models had no horn relay at all. HOWEVER, if you are experiencing weak horns, a clicking sound or no horn at all due to weak voltage, you can install this relay and send 100% voltage to your horns increasing their volume even louder than new.
