- Complete with mounting hardware
- Essential component of radio suppression system
★ Correct earthing is crucial in a 6 volt system. This ground cable ensures a reliable electrical connection between the radio box and the chassis.
Application
Suitable for military jeeps fitted with radio connection box, introduced from approximately March 1943 (MB from serial number ~288,835). The radio box was located under the passenger seat beside the exhaust system, with the ground cable connecting the protruding terminal through the floor to the tinned chassis section.
Installation notes
The ground cable is attached to the terminal protruding through the floor from the radio box and runs to the tinned section of the chassis beneath the passenger seat. Note correct fitment on vehicles with deep mud exhaust system (mid-1945), where the silencer is located under the rear seat.
Compatibility
Only suitable for vehicles originally equipped with a radio connection box. Not all military jeeps had this provision — check whether your vehicle has the radio connection box beneath the passenger seat. Vehicles without this box do not require this specific ground cable.
Historical context
The radio connection box was introduced from mid-1943 as part of the Radio Suppression II system on military jeeps. This system reduced radio frequency interference and enabled the use of communication equipment.
