4 wires will give these functions, so the simplest scheme is a 4-pin connector. The most common 4 wire connector is the 4-Pin Flat Connector as shown here. Trailers that use this are usually fairly light weight and don’t have brakes or other power accessories. It’s the most common style for “consumer” type trailers.
How much weight can you tow without trailer brakes?
The weight limit for which trailers must be installed with brakes begins at 1,500lbs in most states. Trailers weighing over 3,000lbs are required to have brakes on all wheel axles. Driving 4,000lbs trailers with no brakes is just reckless and could lead to severe damage or injury.
