This relay is marked 12V 30A with 4 blade terminals labeled 30, 85, 86 and 87. Confirm the original relay number, 4-pin normally-open layout, voltage, current rating, terminal direction and bracket style.","[FUNCTION / CIRCUIT CHECK] Designed for 12V relay circuits using a 4-pin SPST normally-open main current relay layout. Depending on the vehicle or equipment relay-box slot, this type may be used for power relay, fuse box relay, relay box relay, lighting, horn, heater, fan motor, power window, A/C or ignition-related circuits. Always verify the exact circuit by the fuse box diagram or service manual.","[COMPARE NUMBER CHECK] Compare before ordering with reference numbers 61311351317, 1351317, 1353789, 61311353789, 0867513, 6050578, 6059235, 43206400, KDWHLO9402, 672599, 0302217/0, 515001750 and 980042.

Pull the old relay straight out and avoid prying hard against the fuse box or mounting bracket. Inspect the socket for heat marks, corrosion, moisture or loose terminals. Do not install if your original relay uses a 5-pin / 87a changeover layout, different voltage, different terminal size or a different current requirement.","[COMMON SYMPTOMS] May help restore circuit operation only when diagnosis confirms the original normally-open relay is failed, damaged, overheated, corroded or missing. This relay will not repair wiring faults, blown fuses, bad grounds, failed motors, failed switches or control-module problems.","[COMPATIBILITY NOTE] Vehicle names, model names and part numbers are used only to verify compatibility. Confirm the original part number, relay marking, voltage, amp rating, terminal layout and fuse box diagram before ordering."]
