Engine harnesses operate in a very hostile environment, exposed to very high temperatures as well as engine fluids, vibration and salt spray.

Engine harnesses sometimes even run inside the engine. Designing and manufacturing engine harnesses with full protection is a core skill of LEONI. Engine harnesses for all market sectors – light vehicles, trucks and off-highway vehicles.

We always ensure the engine harness is fully protected – this can include custom designed grommets, formers and protector brackets.

Another example of engine harness protection is our innovative overfoaming technology for pre-formed harnesses. This ensures that all wires are fully protected against extreme temperatures, dirt, moisture, vibration and abrasion. Easier fitting in the tightest of spaces is another benefit of this technique.
