That shouldn't matter, because wiring loom tape isn't sticky in any case. You just need a little blob of glue on one end to stop it from unwinding itself. There is supposed to be a technique to making the end stay together, but I've never managed it so I just use a little blob of superglue.

What does the end look like? In that position, could it be not actually a wire, but something like the throttle cable or choke cable, or even the speedometer cable?
