Key item features

  • Precise Grounding Control: The MSD 8950 operates as an RPM-activated switch kit, precisely supplying and removing electrical ground from a circuit.
  • Dual Circuit Activation: It incorporates two dedicated activation wires, one for grounding a circuit and the other for opening a circuit.
  • RPM-Triggered Operation: Requires an RPM module for activation, enabling the switch to engage a connected circuit when the engine reaches a specific RPM threshold.
  • Versatile System Applications: Capable of diverse functions, including powering solenoids, bulbs, or activating an MSD Timing Control at programmed RPMs.
  • Broad Engine Compatibility: Designed for use across 4, 6, or 8-cylinder engines and compatible with both stock inductive and MSD ignitions.
  • Electrical Amperage Capacity: The switch reliably handles electrical loads up to 1.5 amps for connected components.
  • Essential Module Requirement: RPM modules are not provided with the kit and must be ordered separately to set desired RPM activation points.

Works very well in my '98 Tahoe

Works extremely well. White lead on the unit to the white (tach) lead from the ECM. Two sub-$100 RPM switches tested similarly, didn't work; support said electromagnetic interference, saw none at all on a good oscilloscope. This unit highly recommended. Am using it with the 8677 adjustable RPM module, because I need to trigger at about 1100.
