Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
61 00... Notes on handling wiring harnesses and cables
In general:
To avoid damage, observe the following instructions:
- Avoid compressive and tensile loads
- Make sure cables are laid without kinks or abrasions
- Ensure non-contacting routing at sharp-edged body parts; use muckets if necessary
- Secure additionally laid cables/leads with cable ties
In addition:
Shielded cables (coaxial cables):
- This may lead to indifferences in noise radiation and interference immunity at contact points in the shield
- To satisfy the requirements of the type approval, it is essential to replace shielded cables completely
Fibre-optic cables:
- Green = MOST (M edia O riented S ystems T ransport) fibre-optic cables
- Yellow = ISIS (I ntegrated S ervice and I nformation S erver) fibre-optic cables
- Orange=repair fibre-optic cables
- Fibre-optic cables are permitted to show only one junction point (bridge), replace fibre-optic cables if necessary
- Smallest permissible bending radius is 25 mm
- Avoid effects of heat ≥ 85 °C
TREATING CABLES AND FIBRE-OPTIC CABLES
FlexRay:
It is possible to repair the FlexRay. In the event of damage, the cables can be joined with conventional BUTT CONNECTORS .
- The cable is a twisted cable. If possible, maintain twisted cable after repair.
Airbag cables:
Ribbon cables:

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
