years ago, i bought a cloth harness tape used by German auto manufacturers. the stuff is top shelf. i used it on my 85 corvette 8 or 9 years ago, and it still looks good today. also use it on my 74 Commando - again, no issues. the brand i used is "tesa" but there are others. go to fleabay, and search "cloth electrical harness tape' - hope this helps.
