ONLINE LED STORE 6-Pack Bosch-Style 5-Pin 12V SPDT Relay Harness Kit — Pre-wired 14AWG Interlocking Sockets

True MODS 6 Pack Bosch-style 5-pin relay harness kit is a ready-to-use set of heavy-duty 12V SPDT relays and interlocking sockets designed for reliable high-current switching in automotive and lighting projects.

This kit bundles six Bosch-style 5-pin SPDT relays pre-wired into interlocking socket harnesses so you can add dependable switching to multiple circuits quickly. Each assembly uses stout 14AWG conductors for the primary load and color-coded leads for straightforward hookup. The relays are rated for 12VDC operation (14V maximum) and provide separate normally-closed and normally-open outputs, making them suitable for accessories, lighting, motors, and other vehicle or low-voltage applications where a compact, serviceable relay solution is beneficial.

How do these relays simplify wiring for vehicle lighting and accessories?

Each relay comes pre-mounted in a plug-in socket with an interlocking base so six relay harnesses can chain together neatly. Color-coded pigtails and a clear pin layout cut down installation time and reduce wiring errors.

• Pre-wired 6" pigtails for fast connections
• Interlocking socket bases for tidy cable routing
• Color-coded leads match standard relay pin functions
• Replacement-friendly plug-in relay design

What electrical loads will these 30/40A relays handle reliably?

The relays are specified to switch substantial DC currents typical of automotive loads—30A/40A depending on circuit conditions—so they can control headlights, driving lights, fans, pumps, and similar devices. Use proper fusing and wiring sized for the actual current to ensure safe operation.

• High switching capacity for lights, motors, and pumps
• 14AWG main conductors for durable current carrying
• SPDT configuration supports both NO and NC circuits
• Suitable for 12V systems with up to 14V maximum input

How are the relay sockets and wires organized for maintenance?

The socket harness bases interlock so grouped relays stay organized and accessible; each relay simply pulls out of its socket for inspection or replacement. Labelling or grouping by circuit makes troubleshooting and swaps fast without cutting wires.

• Plug-in relays for quick service or replacement
• Interlocking bases keep multiple relays secure and aligned
• 6" pigtails give room to route and label connections
• Wire colors: black ground, red power, white trigger, yellow NC, blue NO

Who is this kit best suited for? The True MODS 6-pack relay harness is aimed at DIY mechanics, mobile electricians, and vehicle lighting installers who need a compact, serviceable relay solution for multiple circuits. It’s also useful for hobbyists and fabricators building custom electrical panels or off-grid projects that use 12V systems. Choose this kit when you want plug-and-play relay assemblies with robust wiring, clear pin identification, and an interlocking layout that keeps installations neat and easy to maintain.
