WIHING ASSEMBLY FOR FOKD CARS. 



There are many users of Ford cars, and a wiring assembly 

 has been prepared expressly for any model car of this make, 

 comprising timer wires and four spark plug 

 wires. These timer wires are supplied in 

 four individual colors fitted into the very 

 best insulating loom. The timer terminals 

 are finished with pure rubber insulated fer- 

 rules, thus eliminating any chance of short 

 circuit. All the other ends have proper ter- 

 minals with soldered connections, making an 

 absolutely tight electrical joint. The loom 

 ends are finished off with pure rubber in- 

 sulating collars. The set is attractively 

 packed in an individual carton. [Humboldt
