Description

Overview

Hella 7 pole SAE plug gives heavy-duty trailer wiring a strong metal plug connection for truck and trailer electrical systems. It suits 12V SAE-style towing setups where the plug needs firm cable support, durable pins and easier handling during regular coupling.

Features

• Die-cast zinc metal housing for heavy-duty trailer electrical connections.
• High-conductivity 100% brass floating pins held between sonic welded inserts.
• Spring cable guard helps protect the cable at the plug entry.
• Larger finger grips help with safer disconnection from a latched socket lid.

Compatibility and Fitment

Match this plug to the socket style and wiring standard before ordering. Also check the cable size, circuit layout and available cable movement, because SAE heavy-duty plugs do not suit every 7 pin trailer socket format.

For wiring, connect each terminal to the correct trailer circuit. Then tighten the cable support so drawbar movement does not pull directly on the terminals.

Compliance and Safety

Disconnect power before fitting the plug or changing wiring. After installation, test each lighting and auxiliary circuit, then confirm plug engagement, cable guard position and terminal security before the trailer returns to service.

Trailer Applications

Heavy trailers, truck bodies and towing setups use the Hella 7 pole SAE plug where a robust 7 pole connector handles regular coupling and uncoupling. Therefore, workshops should confirm the SAE connector format before replacing lighter round or flat trailer plugs.
