Use when it's inconvenient to connect the battery to the glow plug, for example when the engine is inside an engine cowl. Includes a dummy glow plug, which is the same size as a standard glow plug so your present starting battery setup requires no modification. Also includes Universal Glow Plug Connector (No. 0274C) and a ground cable. All necessary connectors are factory installed. For airplanes, helicopters, boats and cars.
