We then switched to a soldered chain and had fewer problems.

Emphasis above is mine.

For the record, CAN is "wired in parallel" if and only if you regard the conductors as ideal. The real world scenario has imperfections like resistance, inductance, and capacitance, that make for a much more complicated electrical reality than "wired in parallel". Particularly at 1Mb/s, those lumped elements and the aforemnetioned reflection problem mean that the CAN topology is best implemented as a terminated bus with short branches. The PWM connectors are not the issue, and many teams use that style of connector in a canonical implementation of CAN with no issue. Go back to the Jaguar and the CAN bus uses RJ style connectors with no issues if the connectors are properly assembled and inserted. Connectors in CAN are perfectly acceptable, it's the network topology that needs to be respected.

In other words, like Alan and others have said, don't tempt fate. Wire CAN as recommended in the documentation for best results.
