Its integrated resistor eliminates the need for a separate external resistor or special wiring harness, simplifying upgrades and restorations on classic cars, hot rods, restored trucks and 12 V conversions. Constructed from heat- and vibration-resistant materials, the canister design balances compact dimensions (6.3 × 3.9 × 2.8 in) and light weight (1.33 lbs) with OE-style electrical connections for quick, familiar installation.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the built-in resistor simplify installation?\u003c\/h3\u003e\n\u003cp\u003eThe internal resistor means you don’t have to hunt for a separate resistor or rewire the ignition circuit.
