[header] How to make a 1 ohm to 100 megaohm resistance decade box [title] Separate each switch from the others if they come to you as connected. [step] Be careful not to break the clips that connect the switches to each other. [title] Start with the lowest value resistors, the 1 ohm resistors and solder them as as shown in the wiring diagram. 
[title] Connect one end of the resistor to pin 9 and the other end to pin 8 of the switch. [step] Connect the next resistor in the chain to pin 8 (two resistor leads are connected to pin 8) and pin 7.
