Unclip & remove the plastic shrouds off the charging wire spade sockets & shrink a piece of thin heatshrink over each to cover the sharp corners. You can usually pull the wires through the spaghetti one at a time but it is a bit of a struggle.
The woven spaghetti tubing should grow bigger in diameter if you compress it lengthwise, also helping. Pulling it once the wires are thru will return it to original size.
