Autoleads Wiring Harnesses, Fascias and Aerials

Choosing Autoleads fitting kits in 2026

Autoleads is the long established UK brand for car audio fitting kits and accessories, used by professional installers across the country. The range stocked at Bass Junkies covers ISO wiring harnesses, antenna adapters, fascia plates, steering wheel control interfaces and amplifier wiring kits. Choose by vehicle make, model and year and you receive a kit that connects the new aftermarket head unit cleanly into the factory loom with no cable cutting or splicing on most modern vehicles.

What is in the Autoleads range

• ISO harnesses. Plug and play looms that connect a new aftermarket stereo to the original factory connector.
• Fascia panels. Single DIN and double DIN trim plates that square the new head unit to the dashboard.
• Antenna adapters. Convert ISO, Fakra or proprietary OEM aerial plugs to the standard DIN connector.
• Steering wheel control adapters. Retain volume, skip, source and phone buttons on the wheel via the CTSCT series.
• Amp wiring kits. Eight gauge and four gauge power, ground, remote and RCA leads for amplifier installations.

Why fitters trust Autoleads

The brand has been on UK installer shelves for decades and the kits are tested against the latest vehicle releases. Crimp quality is high, the connectors latch securely and the colour codes match the factory loom on most cars. The result is a clean fit, no aftermarket buzzes through the speakers and a stereo that returns to perfect condition if it is later removed.

Brand quality at a glance

• Autoleads. UK trusted standard for fascia and harness kits across hundreds of vehicle platforms.
• Connects2. Sister option for steering wheel control and CAN bus interfaces.
• PAC Audio. Reliable American steering wheel control adapters used on premium installs.
• Axxess by Metra. Specialist interfaces for Ford, GM and luxury European models.
• Stinger. High end power wiring kits that pair with Autoleads harnesses for a complete fitted install.

Steering wheel controls and CAN bus

Most cars built since the mid 2000s carry a CAN bus that wakes the audio system, lights the screen and routes the steering wheel buttons. The Autoleads CTSCT, CTSPG, CTSFD and CTSCT002 style adapters translate the original CAN messages into the resistive or PAC signal that the new aftermarket head unit understands. On many vehicles the adapter also keeps the parking sensors, climate display and reverse line live.

Amplifier wiring kits

The Autoleads amp wiring kit range covers four gauge for big boots running a sub and a four channel, eight gauge for one or two amplifiers on a daily driver and ten gauge for a clean single amp setup. Each kit includes an oxygen free copper power cable, the matching ground lead, an inline fuse holder, a thin remote turn on wire and a length of RCA. The conductors are pure copper not copper clad aluminium so the voltage stays high under load.

Compatibility and fitting

• Fascia adapter. Squares the head unit to the dashboard trim on modern tapered dashes.
• ISO harness. Plug and play connection to the factory loom on most UK vehicles.
• Steering wheel control adapter. Retains all wheel buttons on cars from the mid 2000s onwards.
• Aerial adapter. Converts the OEM antenna plug to the standard DIN connector used on aftermarket stereos.
• Active system adapter. Required where the factory amplifier already drives the standard speakers, so the new install sees a clean line level signal.

Installation guidance

Before you cut anything, photograph the original fascia and wiring loom for reference. Pull the OEM head unit out using the correct DIN keys for double DIN dashes or trim removal tools for vehicle specific cages. Match the Autoleads harness wire by wire, crimp with a quality ratchet tool and seal the joins with adhesive lined heat shrink. Test the radio, Bluetooth, phone and steering buttons before refitting the dash trim.
