Bundle & protect an automotive wiring harness

The need: You need to wrap, bundle and protect a car or truck wiring loom so it stays tidy, survives heat and abrasion, and won't rattle.

Wrapping a wiring harness needs a cloth tape that bundles firmly, resists abrasion where wires rub against edges, tolerates the temperature of its zone, and — ideally — tears cleanly by hand so the assembly line runs fast.

Match the tape's LV 312 temperature class (T1–T4) to where the harness runs, then choose the backing: PET for abrasion, fleece for quiet interiors, acetate for tight insulation.
