It was essential to ensure that both ends of the connector matched to avoid any installation issues later.

Material and Build Quality

When I started examining different 4-pin connectors, I noticed that the material and build quality varied significantly. I preferred connectors made from durable materials, like heavy-duty plastic or corrosion-resistant metal. This choice not only ensured longevity but also protected my investment against the elements, which I found crucial for outdoor use.

I valued ease of installation when selecting a 4-pin connector. Many connectors come with clear instructions, which was a big plus for me. I also looked for designs that allowed for straightforward wiring without complicated setups. Considering my DIY skills, I appreciated connectors that did not require professional installation.
