I contacted flir, I had the same issue, they said they will not sell replacement parts,
the push connector to the circuit board has J2 stamped on it with a standard cell phone type cable that ends with a lightning connector.
Any luck finding this part?

here is a picture of it, I tried soldering a extension from a cut off apple lighting cable but the wires are too darn thin for my soldering skills at least.
