🔧 STS Parts 10SI Diode Harness Plug – Anti-Feedback Solution for Delco Alternators This 2-pack of STS Parts anti-feedback diode harness plugs is designed for use with Delco 10SI alternators commonly found in AMC, Jeep, and Eagle vehicles. These pre-wired diode leads eliminate the issue of ignition "run-on" caused by back-feeding voltage from the alternator to the ignition circuit — a common problem when installing high-output alternators or performing alternator upgrades. Each lead includes an inline diode that blocks reverse current, ensuring clean power cut-off when the ignition is turned off. Perfect for retrofits, restorations, or electrical upgrades where ignition feedback is an issue. ✅ Compatible With: Comaptible with Delco 10SI Alternators Comaptible with AMC Jeep Eagle applications (verify alternator model & wiring layout) Replaces OEM #: 46-1873, Jeep-Eagle 8128393 Specifications: Wire Length: Approx. 8–10 inches Diode Type: In-line one-way current blocking Voltage: 12V systems Application: Ignition feedback suppression ✅ Package Includes: ✔ 2 x Anti-Feedback Diode Wire Harnesses
