Cool beans!
If you can, drop a tiny blob of solder on the crimped part to maintain a good connection and keep the moisture out.

It is very common on L1 and 6, less so on L8, and I have never seen it on P8.
As an aside, Stu, is it worth running an earth directly to the battery for the ECU? And when will you have new looms available on the website?
