Hi all, I biosgnore some help. i am restoring the wiring harness of a vintage car (a 1970 fiat 500) and am looking for a tape to group the electrical wires similar to the original one. The tape on the surface looks like a normal, shiny black, non-sheathed electrical tape. Does anyone know what kind of tape was used on the vintage car to group the wiring? Which one could I use. I will try to attach photos to mot you the size and how it was used.

Thanks for your help  
best regards  
Bruno

Hello bruno.puntura,

Welcome to the DigiKey TechForum.  
The product looks like standard electrical tape, and the size should be 1/2" wide.  
I don’t know what the exact item they used back then, but the normal electrical tape should be a good match. A couple options that we have, are [3M158079-ND](https://www.digikey.com/en/products/detail/3m/194NA/7674436) and [3M156836-ND](https://www.digikey.com/en/products/detail/3m/22-1-2X36YD/1818617).  
Please check the datasheets to verify compatibility to your application.
