Frequently Asked Questions

Why do I need a trailer isolator instead of wiring direct to the OEM turn signal module?

Factory turn signal modules are not rated for trailer current draw. An isolator protects the module from overheating and failure, which typically costs hundreds of dollars to replace.

Does this come with a 5-wire or 4-pin connector?

NAMZ offers both options. Confirm your trailer connector type before ordering — 5-wire has individual brake, turn, and ground leads; 4-pin is a molded flat connector.

What wires do I need to run?

The isolator taps into your battery, brake light circuit, running light, and both turn signals. Ground is also required. A wiring diagram is included.

Will this work with aftermarket turn signal modules?

Yes. The isolator protects any turn signal module by isolating trailer load at the relay bank rather than at the module itself.
