Production drawings.
Here we will manufacture the tacho boards on the same PCB as the Nitrous dongle. The tacho will snap off.
Both units will be factory soldered connections with the JST installed ready to use.  
A specially made grommet to fit the telephone cable into a Scorpius dongle enclosure required a minimum production run of 100,000 units so we’ve decided to simply heat shrink the dongle PCB and add a 3D domed sticker to dress it up.
