4pcs CM1-R-12V Micro-ISO 5-Pin SPDT Automotive Relay 12V 35A, with Resistor, Sealed Plug-in – Compatible with OE MR515994 (Select Mitsubishi), ACM13221; Cross 4133-S-DC12V-C-R-ZZ

CM1-R-12V Micro-ISO Automotive Relay — 5-Pin SPDT, 12V, 35A (with Internal Resistor)Match by OE and footprint to restore reliable switching in fan, HVAC, lighting, and starter-control circuits. This 5-pin SPDT (1 Form C) Micro-ISO relay uses a 12V coil and integrates a resistor for coil suppression.Key SpecificationsCoil Voltage: 12V DC (usable range 10–16V DC)Contact Form: SPDT (1 Form C), 5 pinsRated Switching (resistive): NO 35A @ 14V DC; NC 20A @ 14V DCOperate Time (typical): ~10 ms; Non-latching; Sealed constructionTerminal Type: Plug-in Micro-ISO; Standard ISO numbering (30/87/87a/85/86)Protective Element: Internal resistor (for coil transient suppression)Typical Uses: Cooling fan, A/C clutch, blower, lighting, horn, starter control (per vehicle design)Body Size (approx.): 20 × 15 × 22 mmOE / Product References (for search & confirmation)ACM13221 → CM1-R-12V product mapping (manufacturer reference)MR515994 → Compatible with Mitsubishi applications that specify this OE relay (confirm by VIN/box legend)Installation & Fitment NotesDisconnect battery negative before service. Locate the under-hood fuse/relay box and identify the slot calling for a 5-pin SPDT Micro-ISO relay.Verify pin count and layout: 30 (common), 87 (normally open), 87a (normally closed), 85/86 (coil).Push to seat fully; do not force. Reconnect battery and test the controlled load (fan, A/C clutch, etc.).Symptoms This Relay Addresses (when original relay fails)Intermittent/no cooling-fan operation; A/C clutch not engagingNo-crank or sporadic starter-control (when used in that circuit)Load cuts out after warm-up; relay clicking but no continuityComplementary Products (related traffic)4-Pin SPST Micro-ISO (e.g., CM1A-R-12V / ACM33221) — use only if your slot requires 4 pinsRelay sockets/pigtails for Micro-ISO (if adding auxiliary circuits; verify wire gauge and rating)Always confirm by OE number and pin configuration before purchase. This item is supplied as an aftermarket replacement and is not produced by the vehicle manufacturer.

• Specs + OE Cross-Refs (make sure your original matches): 12V DC coil; 5-pin SPDT (1 Form C); 35A @ 14V on NO side (20A on NC side); sealed housing; plug-in Micro-ISO footprint; internal resistor for coil suppression. Cross-reference by OE/Product No.: ACM13221 (Panasonic product number for CM1-R-12V), MR515994 (OE reference). Terminal layout follows standard ISO: 30 (COM), 87 (NO), 87a (NC), 85/86 (coil).
• Operation & Installation Location: Drops into the under-hood fuse/relay box (junction box/IPDM) positions that specify a 5-pin SPDT Micro-ISO relay with resistor. Typical controlled loads include cooling fan motor, A/C clutch, blower, headlights, horn, starter control and other 12V accessories, depending on the vehicle circuit design—always verify your box legend and pin count before installing.
• Compatibility—by OE MR515994 (for search & fit confirmation): Compatible with Mitsubishi applications that call for OE MR515994. Common fitments include Outlander Sport (2011–2025) and Eclipse Cross (2018–2025)—used in engine-bay relay positions for starter/fan control per OE listings (verify slot function on your vehicle).
• Additional Mitsubishi coverage by MR515994 (examples): Compatible with Mitsubishi Lancer/Lancer Sportback (select 2003–2007 model years) and other platforms listed under MR515994 on OE catalogs; always confirm with VIN or relay footprint before purchase to ensure your slot calls for a 5-pin SPDT Micro-ISO
• Complementary Items for related traffic (not direct substitutes): For circuits that require 4-pin SPST Micro-ISO, see OE/product numbers CM1A-R-12V / ACM33221 (Compatible with vehicles that use a 4-pin slot). Use only when your original is 4-pin SPST; do not interchange with this 5-pin SPDT relay unless your wiring diagram specifies it
