American Motors Wiring Harnesses & Electrical - OEM-Fit Harnesses & Components

Restore your American Motors ’s electrical system with precision-engineered wiring harnesses and electrical components designed specifically for your vehicle. Each harness is manufactured to match the original routing, connectors, and circuits of your American Motors —restoring the wiring behind the dash, under the hood, and through the body to factory-correct, or factory-improved, condition.

Our American Motors electrical lineup includes complete wiring harness sets, battery cables and ground straps, switches, electrical devices, and update/conversion products such as alternator upgrades and electronic ignition conversions. Every component is manufactured and tested to deliver dependable, factory-correct performance, and is organized by your vehicle’s exact year to ensure the harness or component you order is the one built for your American Motors —not a close approximation.
