BLOCK JUNCTION 2 POST FORD
The Junction Block is used at two locations on the WWII Jeep. One is used on the left hand fender for connecting head and marker lights and the another is used on the firewall for connecting the Ignition Switch and Coil wiring on all Jeeps using Push Pull Headlight Switches.

Application
This 2-post junction block was used on WWII jeeps at various locations. One example was mounted on the left wing for the connection of headlamp and marker light wiring. A second example was mounted on the firewall for the connection between ignition switch and coil, specifically on vehicles equipped with the push-pull light switch (as opposed to the rotary switch). Early jeeps even had a third 2-post block on the firewall next to the larger 6-post junction block.
Installation notes
The junction block is secured with 2 screws at the desired location. Wiring is connected to the two screw terminals using ring terminals. Ensure proper earthing and insulation of all connections. When mounting on the wing: use the correct rubber grommet for the wiring.
Compatibility
Please note: there are differences between MB (Willys) and GPW (Ford) versions in terms of material and colour. MB blocks are made of phenolic resin with paper layers, GPW blocks are made of compressed fibre material in natural colour. Both types are functionally interchangeable but differ in terms of authenticity. Check which version suits your vehicle for a correct restoration.
Historical context
The 2-post junction block was a standard electrical component in the 6V wiring system of WWII jeeps. The blocks were manufactured from phenolic resin-impregnated fibre material, a material also used for switches and other electrical components from that period.
