Do you have a picture of these in place in one of your cars? 

It would just help me understand the circuitry arrangement better.

Jeremy,
Not at home at the moment so can't take pic of an installation.
But below is sort of how it looks.
1 Connector to the braids paired to one feeding the front of the chip.
1 connector to the motor paired to one from the back end of the chip.

Arranged like this,  chip swap should be simple and quick affair.
A bypass cable could also be made to run analogue or to to skim tyres while in the car.
Ferrite man should be chip-side of the connector, not motor-side so that swapping the chip out removes the ferrite man
