M22759/32-18-74 VIOLET/YELLOW BTF STRIPE

M22759/32 Tefzel Wire — 18 AWG, Violet/Yellow Stripe

The M22759/32-18-74 Violet/Yellow BTF Stripe — SKU: M22759/32-18-74-PRSP is a genuine MIL-spec M22759/32 dual-wall Tefzel-insulated stranded wire in 18 AWG with a violet/yellow striped insulation, supplied by Arctic Performance Parts as a pre-striped BTF (Build To Fill) shelf stock wire for professional motorsport wiring harness construction. M22759/32 is the heavier-wall variant of the Tefzel wire family, providing enhanced mechanical insulation protection for power and mixed-function wiring in demanding motorsport electrical environments.

M22759/32 — Dual-Wall Tefzel

Where M22759/16 uses a single thin-wall ETFE construction optimised for lightweight signal wiring, M22759/32 applies a heavier dual-wall Tefzel insulation that withstands greater mechanical stress — abrasion against chassis edges, cut-through under grommet compression, and sustained contact with adjacent components in a tightly routed power harness. Both variants share the same ETFE chemistry, retaining the 150°C continuous temperature rating, exceptional fuel and oil resistance, and chemical stability of the full Tefzel wire family. The thicker wall of M22759/32 extends the wire’s service life in the more demanding routing environments associated with 18 AWG power and actuator circuit wiring in race cars.

Violet/Yellow — Colour Code 74

Violet/yellow (code 74) at 18 AWG M22759/32 identifies output and actuator feed conductors within the violet dedicated function circuit family — the yellow stripe indicating a switched output or component supply function within the violet-base power circuit group. Violet-family power circuits in race car harnesses typically cover dedicated function outputs — pit lane speed limiter solenoids, launch control arming relays, boost control actuators, and similar function-specific switched outputs. Violet/yellow identifies the switched output conductors within this group, allowing technicians to distinguish active output conductors from supply inputs in the violet-family connector without consulting a wiring diagram.

18 AWG — Gauge Selection

18 AWG M22759/32 covers the mid-range of the motorsport wiring spectrum — used for relay output feeds, switched actuator power, ignition coil primary circuits, sensor supply runs, and mixed-function control conductors where the dual-wall Tefzel construction provides added insulation robustness for wiring routed near heat sources, sharp chassis edges, or through abrasive grommet passages in a race car. The stranded tin-plated copper conductor provides the flexibility and vibration fatigue resistance essential for motorsport harness routing through the bends, grommet passes, and chassis runs that power wiring must navigate in a professionally built race car harness.

BTF Shelf Stock — Ready to Ship

The PRSP designation confirms this wire is held as pre-striped shelf stock at Arctic Performance Parts, available for immediate dispatch without the lead time of a custom stripe run. Professional harness builders working to tight build schedules can order the violet/yellow colour combination and receive it promptly — a key advantage when a specific colour is needed to complete a build on deadline. Arctic Performance Parts stocks a broad range of M22759/32 striped colours across standard motorsport power wiring gauges.
