Missing few parts; main loom, wire restrictor between pectel unit and coil, 8-pos. adj. knob.

I have wiring diagrams, so loom ain`t big problem, but can`t find out wire restrictor ohm reading nowhere, and same thing with 8-pos. adjust knob.

Can anyone help with this?
Here, in finland, ain`t much knowledge of these...
