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 lines
Joins in the shield can cause problems with regard to noise radiation and interference immunity. Consequently, distinctions have to be drawn between the following types:
Coaxial lines
- Shielded RTK031 coaxial lines may only be repaired with special crimping tools.
CVBS lines
- CVBS cables may not be repaired.
- CVBS cables must be replaced in their entirety.
HSD lines
- HSD cables may not be repaired.
- HSD cables must be replaced in their entirety.
Optical fibre cable:
- Green = MOST (M edia O riented S ystems T ransport) optical fibres
- Yellow = ISIS (I ntelligent S afety I ntegration S ystem) optical fibres
- Orange = repair fibre-optic cables
- Optical fibres are permitted to show only one junction point (bridge). Replace optical fibres if necessary
- Smallest permissible bending radius is 25 mm
- Avoid effects of heat ≥ 85 °
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 AND HEAT-SHRINK TUBING .
- FlexRay lines may only reveal one separation point (bride); renew complete line if necessary
- The cable is a twisted cable. If possible, maintain twisted cable after repair

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • 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.
