Specifications & compatible OE: 12V coil; SPDT (1 Form C); NO 35A / NC 20A; coil resistance 123 Ω; sealed “S” enclosure; internal “R1” resistor for transient suppression; Micro ISO/280 footprint (approx. 23×15.5×25.4 mm). Compatible with Freightliner OE 23-13265-011; Compatible with International/Navistar OE 3571998C1 and 2026910C1; Compatible with Volvo OE 20754835; Compatible with S&S/Newstar S-26601 (verify by OE and pin layout).
Install location & pinout (changeover 5-pin): Typically installs in the fuse/relay box or power distribution module that accepts ISO 280 5-blade relays. Standard layout: coil 85/86; common 30; 87 (NO); 87a (NC). The built-in “R1” resistor suppresses coil back-EMF to help protect control electronics. Disconnect the battery, match the diagram on the old relay, seat fully, then function-test.
Vehicle fitment by OE (verify before purchase): Compatible with Freightliner Cascadia, Compatible with Freightliner Columbia, and Compatible with Freightliner M2 106 (2012) when the socket specifies OE 23-13265-011; Compatible with International/Navistar applications where OE 3571998C1 or 2026910C1 is called out (e.g., Compatible with IC Bus CE/BE/FE/RE series); Compatible with Volvo applications calling for OE 20754835. Always confirm by OE number and pin diagram, not model name alone.
What it typically restores: Reliable switching for lamps/lighting, horns, HVAC blower and cooling fans, fuel pumps and other medium-current loads on 12V systems using an ISO 280 Micro SPDT relay; common failure symptoms include inoperative horn/fan/pump, intermittent power to a module, or a stuck-on accessory from welded contacts.
Form/fit, environment & complementary parts: ISO 280 Micro blades (three 3/16" + two 1/4"); harness-mount footprint. Operating range −40°C to +125°C; typical coil current ~97.5 mA at 12V. For clean installs or repairs, pair with Compatible with TE Connectivity ISO 280 5-pin relay connector V23333-Z1001-B045/B046 or Compatible with Delphi Metri-Pack 280 5-way relay socket 12110539; Compatible with 5-pin ISO 280 weatherproof pigtail kits (sold separately).
