Frequently Asked Questions (FAQ)
Why are stainless steel screws better than standard aluminium ones?
Standard aluminium terminals are fragile and frequently snap or strip when you tighten them down on heavy-gauge wire. Stainless steel screws provide a much stronger physical hold, handle higher torque during installation, and drastically reduce corrosion risk over time.
Will this 7-pin flat plug fit my standard Australian vehicle socket?
Yes. This plug strictly follows the standard Australian physical format and wiring configuration, making it fully compatible with all standard 7-pin flat vehicle sockets installed across Australia.
Can I use a 7-pin flat plug with a 12-pin socket setup?
Yes, a standard 7-pin flat trailer plug will physically plug into the top row of a standard 12-pin vehicle socket. However, it will only operate the primary 7 lighting circuits (pins 1 to 7).
