The easiest way to do it since the rule reads "wired around the mount"
1 - Remove the oil filter mount
2 - Wrap some safety wire around the mount near the 90 degree angle where it mounts to the frame
3 - Borrow someone's safety wire pliers and twist a 'braid' into the wire that is around 3 inches long
4 - reinstall the mount to the frame and install the oil hoses
5 - Install the oil filter
6 - Slip the hose clamp over the filter and slide it up the filter lacing the 'bradeed wire' under the hose clamp.
7 - Tighten the clamp, pinching the twisted wire or 'braided wire' as I call it, between the clamp and the oil filter
This way, if you need to change a filter for regular oil filter maintenance, you will not have to re-braid a wire or twist another safety wire around the mount again... just remove the clamp from the 3 inch piece of braided wire.
It will also come in handy if a rock or debris pokes a hole into your filter during a race and you need to pull into the pits and replace a filter real quick
The rule states "around the mount" but does not state "around the clamp"
Another method would be to drill a small hole through the mount on one side while it is removed ( avoiding drilling through an oil passage) for a place to run the safety wire through so you don't have to run a wire around the entire mount or around a hose nipple on the mount
