M22759/16-14-04 BLACK/YELLOW BTF STRIPE

M22759/16-14 Black/Yellow Stripe Tefzel Wire – 14 AWG MIL-SPEC ETFE Wire for Medium-Current Motorsport Circuits

The M22759/16-14-04 is a 14 AWG Tefzel ETFE aerospace-specification wire with a black base and yellow tracer stripe, supplied pre-spooled for professional motorsport harness fabrication. At 14 AWG, this wire steps up in current-carrying capacity from the 16 AWG range – covering medium-current circuit applications including fan motor feeds, fuel pump supply lines, relay output circuits, and primary ECU power feeds in race cars and performance vehicles across Norway, Sweden, and Denmark.

Black/Yellow: The High-Visibility Advisory Stripe Combination

Black with yellow stripe is one of the most visually striking colour combinations in the M22759 wire palette. The high contrast between black insulation and yellow tracer makes this wire immediately identifiable in a dense harness bundle even under poor workshop or trackside lighting conditions. In professional wiring identification schemes, black/yellow is commonly assigned to advisory and caution-level circuit functions – secondary ignition supplies, sensor power feeds requiring attention during diagnostics, or any circuit category the builder designates as a high-visibility identification priority within the harness.

14 AWG Tefzel: Medium-Current Capacity in a Lightweight Package

14 AWG Tefzel wire carries significantly more current than 16 AWG while retaining the lightweight, thin-wall insulation properties that make Tefzel the preferred wire for serious motorsport harness builds. This makes it the correct gauge for medium-current circuits that need more capacity than sensor-level wiring but are routed through areas where harness weight and diameter still matter – such as engine bay main looms, firewall-crossing trunk cables, and chassis-to-engine bridge harnesses.
