The Power Cord Extension Lead is one of the core components of the Building Block Wire Harness system, designed to eliminate hard-wired, permanent harnesses.

This extension lead connects directly between compatible power cord leads, giving you added length to properly space lights along gunnels, cages, racks, or mounting bars. Because everything uses waterproof plug-and-play connections, you can change layouts, add lights, or reroute wiring without tools or downtime.

What does this extension lead do?
It adds 40 inches of length between compatible power cord leads, allowing you to space lights farther apart and route wiring cleanly.

Do I need this for every light?
Not always. Extension leads are most useful when lights are spaced more than a few inches apart or when routing wiring around obstacles.

Is this for power or control wiring?
This extension lead is specifically for power cord leads, not control dial leads.

Does this replace a tee connector?
No. Tee connectors split power or control signals. Extension leads simply add length between components.

Why use the Building Block Wire Harness instead of permanent wiring?
It allows you to change how lights are grouped, controlled, or positioned on the fly, without soldering or sending harnesses back for modification.
