On a 70 shelby factory tail lamp harness the harness, On the rear under the lamps & sockets half of the harness,, is wrapped in what looks like to me , a 1 inch cloth type tape with adhesive . Does not look like friction tape more like cloth and actually looks like the tape i use to use on my hockey sticks back in the day,,, lol, ,,,, or is it friction tape ??? Any help and a source of what is correct would be awesome, Thanks, Bob Wilson,
