Genuine OEM 120007826 12V 4-Pin Relay Compatible with GM/Hyundai Vehicles Main Current ABS Multi-Purpose Relay, Cross-Ref 0 332 019 166 / MR84

What You Get: 1× Main Current Relay (OE 120007826), 12V / 4-Pin / Normally Open (NO) / 40A.Cross-References: 0 332 019 166; MR84 (RLPS/4-12). Catalogs associate OE 120007826 with General Motors/GMC and Hyundai applications for main-current/ABS/multi-purpose circuits. Always match the OE number printed on your original relay before ordering.Electrical & Ratings: 12V system, 4-pin blade layout, NO contact; 40A main-current duty (per MR84 spec and equivalent listings).Typical Location: Under-hood/engine-bay fuse & relay center (verify position in your vehicle’s cover diagram or service manual).Typical Functions: Low beam, horn, windshield wiper, heated rear window, heater/AC blower and other high-draw accessories (as equipped).Verification Steps: Match OE number (120007826) on your removed relay; confirm 4 pins and NO circuit; confirm 12V system; compare the footprint and keying to your relay socket.Compatible With (by OE): Vehicles that specify OE 120007826 for the main-current/ABS/multi-purpose relay position. Example: Opel/Vauxhall Corsa E 2015–2019 (engine-bay fuse box) when the original relay is stamped 120007826. Model-level usage differs by market and build date—OE match is required.Complementary (Not Interchange): Other relays often serviced in the same fuse box include GM multi-purpose families (e.g., 13500114/13500126) and Hyundai/Kia families (e.g., 39160-2G000, 95230-3A400) for their respective circuits—use only where your OE calls for them.Notes: This is an aftermarket replacement built to the OE form and function indicated by the OE numbers above. Brand names appear only as cross-references to help identify the correct part.

• Specs & OE references — 12V, 4-pin, normally open (NO), 40A “main current” relay. Compatible with vehicles that specify OE 120007826. Cross-Ref: 0 332 019 166; MR84 (RLPS/4-12). OE families that reference 120007826 include General Motors/GMC and Hyundai; several catalogs list it as “main current/ABS relay.” Always match the printed OE on your original part before purchase.
• Location & functions — Typically installed in the under-hood/engine-bay fuse & relay center. Common circuits controlled by this relay type include: low beam, horn, wiper, heated rear window, cabin blower/AC fan, and other high-draw accessories (function set documented for MR84. Replace when these systems show intermittent/no-power faults and the circuit OE calls for 120007826.
• Compatibility guidance (how to verify) — Compatible with vehicles that explicitly specify OE 120007826 for the main current/ABS/multi-purpose position; used across GM/GMC and Hyundai families. Because manufacturers may fit different relays by trim/build date, confirm the OE number printed on your original relay body (120007826), 4-pin layout, and 12V system before ordering.
• Verified example application — Compatible with Opel/Vauxhall Corsa E 2015–2019 (engine-bay fuse box) when the original relay is marked 120007826; also cross-referenced to 0 332 019 166 and MR84 in retail catalogs. (Always match OE on the removed part.)
• Cross-reference numbers to match during checkout — Compatible withGM/General Motors: 120007826 (also seen alongside GM catalog families for main-current relays); 0 332 019 166; MR84 (12V/40A/4-pin NO). Some cross-reference tables also group Hyundai/Kia power-relay families near 120007826; verify your OE stamp before substitution.
• Complementary items to bundle (not direct substitutions) — To refresh related circuits in the same fuse box, consider adding compatible relays that serve other positions: GM multi-purpose relay families (e.g., 13500114/13500126 as applicable to your vehicle’s OE); Hyundai/Kia power-relay families like 39160-2G000 or 95230-3A400 for their respective circuits. These are complementary parts, not 120007826 replacements—match OE by position.
• What this relay fixes (when OE calls for 120007826) — No-start or intermittent start due to main-current feed drop, inoperative blower/AC fan, inoperative wipers or horn, low-beam dropout, or heated rear window not engaging. Confirm the symptom disappears with a known-good relay and that the affected circuit’s OE specifies 120007826.
