REDARC BCDCWK-002 BCDC 25A Across Engine Bay DC-DC Charger Wiring Kit

The REDARC BCDCWK-002 is an engine bay-specific wiring kit engineered for clean, reliable installation of a 25A BCDC DC-to-DC battery charger when the start battery and auxiliary battery are positioned at opposite ends of the engine bay — specifically where batteries are more than 0.6 m (2') and less than 3.5 m (11') apart.

Compatible with the BCDC1220, BCDC1220-IGN, and BCDC1225D chargers, this kit includes everything needed to make a professional-grade connection between your BCDC charger and both batteries, without cutting corners or sourcing additional hardware.

Kit Includes:

• Brown cable — 2.5 m (8'2") length, pre-crimped at one end
• Black cable — 2.5 m (8'2") length, pre-crimped at one end
• Red cable — 3.5 m (11'5") length, pre-crimped at one end
• 2× 150 mm (6") short red cables
• Terminal block with plastic cover
• MIDI fuse kit: 4× MIDI fuses (2 spares) and 2× MIDI fuse holders
• M5 × 25 mm socket head screws (×4), M5 nylon locking nuts (×4), M5 flat washers (×4)
• 2× Wago® connectors and boots

Key Features:

• Pre-crimped cables reduce installation time and ensure a secure, factory-quality connection at one end
• Cut-to-length design — the terminal block allows the free end of each cable to be trimmed to the exact length needed for your specific installation
• Terminal block connection enables easy cable diameter transitions without soldering or complex lug terminals
• MIDI inline fusing protects both the start battery and auxiliary battery circuits
• Compatible with BCDC1220, BCDC1220-IGN, and BCDC1225D charger models

Note: The auxiliary battery ground cable and solar-to-Anderson cable are sold separately. REDARC recommends installation by a qualified auto electrician or technician.
