It is difficult to remove the device from a vehicle

I find it difficult to remove the device from a vehicle. It is possible to unplug the wiring harness from the PCB but only after unplugging from the 8 fiddling individual connections into my car's wiring loom. This makes it harder to remove the device for programming or testing as by necessity the wiring harness is short to allow it to be hidden under the dashboard.

A better choice might have been to use a DB-9 connector in place of the 10-pin 0.1" Molex header. This would allow external disconnection of the wiring harness from the device in a single operation. This would be similar to the DB-37 used by the MegaSquirt ECU.

It might be possible to wire a chassis mount DB-9 to the PCB but a PCB mount DB-9 connector would be neater.
