Does anybody know if there is an aerospace spec, SAE or otherwise, for the installation of safety wire? We tie down a connector jam nut for a device we manufacture but I cannot justify the method we use.

Give NASM 33540 a try.
Many folks write their own internal doc.It can allways get intresting when there is a differance of opinion on what is the "right" criteria to use. The approved design data allways wins so for us our TSO data is the law.

Take a look at the attached. I'm on the road and don't have access to my mechanics manuals, but I'm an A&P and lockwire can look like what I have here.

Try to google FAA advisory circular AC 43.13-1B Chapter 7. The complete hard-copy volume "Acceptable methods, techniques, and practices — aircraft inspection and repair". Individual chapters are usually available for download.

Thank you Mr AEOS_QA for the recommendation of the FAA advisory circular AC 43.13-1B Chapter 7. Very useful indeed.
