SPRS TXL Automotive primary wire is a stranded special purpose automotive copper wire that is insulated with chemically crosslinked polyethylene, manufactured to the SAE J1128 standard. The thin wall insulation has a smooth surface which resists moisture, oil, grease, and most fuels, acids, and solvents. Additionally, the reduced diameter insulation has excellent temperature tolerance making it an ideal choice for use in wiring harnesses in both the passenger and engine compartments. Temperature Rating: -40°C to 125°C (-40°F to 257°F. SPRS stocks 10, 14, 18, and 22 gauge in multiple colors for most automotive needs with other sizes available for special order.

 

SPRS TXL 22 AWG automotive wire is useful in wiring harnesses for connecting to automotive sensors and controls such as pressure and temperature sensors, small solenoids such as IAC, and 5vdc power and ground. Wire runs in excess of 15 feet and components like fuel injectors and ignition coil control wires should be run with a larger gauge wire such as TXL 18 AWG.

 

SPRS TXL 18 AWG automotive wire is useful in wiring harnesses for connecting automotive components which require greater current, such as fuel injectors and ignition coil control wires. Devices which draw more than 10 amps and/or wire runs in excess of 15 feet should be consider a larger wire such as TXL 14 AWG or TXL 10 AWG.

 

SPRS TXL 14 AWG automotive wire is useful in wiring harnesses for connecting automotive larger components such as relays, fuel pumps up to 150 GPH, ignition coils, COP/CNP power, headlight, and smaller accessory fans. Devices which draw more than 10 amps and/or wire runs in excess of 15 feet should be consider a larger wire such as TXL 10 AWG.

 

SPRS TXL 10 AWG automotive wire is useful in wiring harnesses for connecting large components with heavy amp draws or large in-rush current such as ECU/ECM, fuel pumps over 150 GPH, COP/CNP power, large cooling and accessory fans. See the table below for amperage based on wire gauge and length.

Wire sizes assume conductors held firmly inside wire loom, and may be secured with other electrical conductors. 5% maximum voltage drop from 13.5VDC with temperatures to 140F or 60C degrees. Critical circuits should use one size larger wire.
