Light those lights, lift those gates

摘要

As trailers become more complex, with telematics and diagnostics systems of their own, more auxiliary equipment and more sensitive electronics, the need to keep those systems running will become more challenging. We are already close to capacity in terms of circuits coming from the tractor, hamstrung by the limits of the traditional 7-pin trailer connector. But engineers are thinking beyond 7-pins to 15 pins, and even self-supporting trailer electrical systems that can power auxiliary systems onboard the tractor. That's a bit of a role reversal, and it may be closer than you think.
