M22759/32-20-90 White/Black BTF Stripe – 20 AWG Silicone MIL-SPEC Wire for Low-Current Signal Wiring in High-Temperature Applications
The M22759/32-20-90 is a 20 AWG MIL-SPEC wire with a white base and black BTF stripe, silicone insulation, and a silver-plated copper conductor. Manufactured to the M22759/32 military specification, it is designed for motorsport, aerospace, and high-performance vehicle wiring applications where fine-gauge conductors must operate reliably in thermally demanding environments. Supplied pre-spooled.
White/Black BTF Stripe at 20 AWG
The white base with black BTF stripe (-90) is one of the most widely used colour combinations in the M22759 wire range and is available across multiple gauges — including 20, 18, and 16 AWG — in the M22759/32 silicone series. At 20 AWG, this wire provides the fine gauge needed for dense ECU connector pin fields and tight harness routing while retaining the white/black colour identity consistent with the same circuit designation across other gauges in the harness build.
20 AWG for ECU and Sensor Harness Fabrication
20 AWG is a common specification for ECU signal connections, sensor outputs, and other low-current circuits in professional motorsport harness construction. In silicone specification, it provides the additional temperature headroom needed for circuits routed near heat sources in the engine bay, without requiring the additional insulation bulk of heavier heat-shielding solutions.
