Automotive wiring for 12V and 24V installations, engineered to be flexible, oil-resistant and cut to requirement. Perfect for installers and DIYers who need neat routing and reliable solder joints. Is Wire4u Automotive Wire the right fit for low-voltage lighting and sensor runs?

⚡ At a Glance
  • Durability: Thinwall construction with plain copper conductors, resistant to petrol, diesel, lubricating oils and diluted acids
  • Best for: Automotive installers and hobbyists wiring 12V and 24V systems
  • Not ideal for: Mains voltage or heavy-current electrical circuits

Thinwall multi-core automotive wire available in flat and round versions. Suitable for a wide temperature range and designed for low-voltage vehicle use.


Neat routing in tight spaces – with thinwall multi-core construction

Thinwall insulation reduces overall diameter across the 2, 3, 4, 5 and 7 core options, while plain copper conductors maintain flexibility across available cross-sections from 0.5mm to 2.5mm. Flat and round formats offer choices for confined runs or panel-back installations.

Easier to tuck behind trim, through conduits and around tight bends for clean, professional-looking installations.

Secure electrical joints – with plain copper conductors

Plain copper conductors take solder well and form low-resistance joints, making them suitable for LED connections and standard automotive crimps. The conductor material supports reliable mechanical and soldered connections.

Secure solder and connector joints reduce the risk of intermittent faults, which is especially helpful for low-voltage lighting and sensor wiring.

Engine-bay resilience – thanks to chemical and temperature resistance

Materials are rated for use from -40°C to +105°C and resist petrol, diesel, lubricating oils and diluted acids, which are common contaminants in engine compartments. The chemical resistance helps protect conductors and insulation where fluids are present.

Suitable for runs near engines and external fittings where exposure to heat and fluids is likely, improving long-term reliability.

✨ The 4 Key Reasons for Wire4u Automotive Wire
  1. Thinwall construction – Easier to route through tight trim and conduit
  2. Plain copper conductors – Better solder adhesion for LED and sensor connections
  3. Chemical resistance – Withstands petrol, diesel and oils in engine compartments
  4. Cut-to-length service – Reduces waste and gives exact cable runs every time
