Hello Liteace and thank you for your post.
This is most unusual for the insulation about these leads to separate in such a fashion.
You are right that the conductor is not threaded and any attempt to rotate them within the insulation may result in fracture.
Thank you for pointing this concern out as I would like to resolve this for you ASAP.
I would like to recover these leads to enable the engineers to understand why this has happened and so provide feedback regarding the manufacturing process if applicable.
With any issue of this nature, can you contact the support line at Pico either via firstname.lastname@example.org
or via the phone on 01480 396 395
The support service will endeavour to provide a faster return of service than the forum as any automotive issues are directed through to the automotive team who can respond and process issues of this nature from received customer contact through to global dispatch.
I hope this helps Liteace and I look forward to your email where I can process this concern
