When electronic engine control came into the auto assembly plants and we had to diagnose/repair any damaged wiring, we were told to always use a solder repair vs a crimp repair. It was felt that due to the sometimes low voltages in these circuits (.2 volt) that crimp repairs could have higher resistance and/or corrode and degrade the circuit over time.

Shrink wrap over the repair of course.

In my private world, I've never seen a soldered connection fail, unlike some crimp connections.
