So I've tried tinning wire to connect to a breadboard, but I'm also considering crimping something like male crimp pins. Is tinning the wire sufficient to make a good connection for the sensors?

soldering the pins have taken some time to build up on thinner gauge wires to get plug into breadboard without slipping out. Fred comments that I'm probably wasting time, but until a Jaguar board arrives, I've got to do something to stay engaged. If you find yourself without firmware to support your car but are eager to run FreeEms feel free to reply. I think a good user community united on the desire to run Jaguar v 0.4, we can work in new ways to support firmware development if we can figure out how.

Are you planning to wire up a breadboard based ECU?

It'll go down great for promo material if he does! Even I'll be impressed! Also, confused, but that's quite normal these days as senility starts to take a firm hold.
