very handy system has a sprung loaded cap to fit to the top of the glow plug by pulling the red lead pushing the cap on to the glow plug then you let go of the lead to allow the unit to clip on.
The remote glowplug unit has a nut to fit the unit to a fuselage or cowl, the negative lead connects to this unit and shoud be mounted under a bolt on the engine the plug cap then screws onto the threaded portion of the unit. This should be secured with threadlock to avoid it from falling off!!
