GRMGRM040026 uses automotive grade 16 gauge wire to minimize resistance and deliver maximum volume to the new horns, while heat shrink crimp on terminals keep every connection reliable over time. A protective wire sleeving gives GRMGRM040026 a clean black look while guarding against abrasion and vibration related stress. Designed to plug directly into the OEM harness, this kit installs and uninstalls in seconds, making it an easy companion to a set of Hella horns and the GrimmSpeed BroTie mounting bracket.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eAutomotive grade 16 gauge wire for minimal resistance and maximum volume\u003c\/li\u003e\n\u003cli\u003eHeat shrink, crimp on terminals for a reliable connection\u003c\/li\u003e\n\u003cli\u003eProtective wire sleeving for a clean look and added durability\u003c\/li\u003e\n\u003cli\u003ePlug and play design that installs and uninstalls in seconds\u003c\/li\u003e\n\u003cli\u003eCompatible with the OEM horn harness connector\u003c\/li\u003e\n\u003cli\u003eCan be adapted for use with a more complex relay harness if desired\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eYear\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2015-2021\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eWRX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2015-2021\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eWRX STI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eGRMGRM040026\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer Part Number\u003c\/td\u003e\n\u003ctd\u003e040026\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWire Gauge\u003c\/td\u003e\n\u003ctd\u003e16ga Automotive Grade\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal Type\u003c\/td\u003e\n\u003ctd\u003eHeat Shrink Crimp On\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003e2015-2021 Subaru WRX and STI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003eNot published by manufacturer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch4\u003eWhat's Included\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e1 GrimmSpeed Hella Horn Wiring Harness (GRMGRM040026)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eAbout GrimmSpeed\u003c\/h4\u003e\n\u003cp\u003eGrimmSpeed is a Minnesota based performance manufacturer known for practical, well engineered Subaru specific upgrades.
