Real-World Testing: Putting Scotchlok 560M Instant Auto-Electric Connectors For #18-16-14 Gauge Wire – #801 to the Test
First Use Experience
I primarily tested these connectors in my home workshop, simulating typical automotive and small appliance repair scenarios. The first application involved adding a set of LED fog lights to a vintage truck, requiring several tap splices into the existing #14 gauge wiring. The second test case involved pigtailing a new power lead for a benchtop power supply, utilizing #18 gauge stranded wire.
Performance under these conditions was surprisingly consistent. The connectors handled both solid and stranded wires within the specified gauge range (#18, #16, #14) without any issue. The primary advantage became immediately apparent: the speed at which a connection could be made. Once the wires were positioned, a simple firm press with a suitable tool (a pair of 3M™ Scotchlok™ E-9R or similar crimping pliers, which I already possess from prior work) locked everything into place.
There was a slight learning curve, mostly around ensuring the wires were seated correctly before applying pressure to achieve the best contact. The integrated blade within the connector is designed to cut through the wire insulation, making the connection without pre-stripping. Initially, I overthought the wire insertion, but a few practice runs confirmed that a straightforward push until resistance is met was sufficient. No real surprises or quirks emerged during this initial phase, which, given my experience with electrical connectors, speaks volumes about their intuitive design.

After several weeks of consistent use in my workshop – incorporating these connectors into various small projects including repairing the wiring on a seldom-used piece of workshop equipment and adding an accessory power port to a motorcycle – their reliability has proven to be a significant asset. The connections remain secure, with no signs of loosening or degradation even when subjected to vibrations from operating machinery.
Durability has been impressive. Despite being dropped a couple of times on the concrete floor (a common occurrence when working on projects), none of the units fractured or showed any visible signs of damage. The blue housing feels robust, and the internal blade mechanism appears to have maintained its sharpness and integrity. I haven’t encountered any issues with insulation resistance or conductivity drop over time, which is a critical factor for long-term electrical integrity.
Maintenance is practically non-existent, which is a major selling point. Once a connection is made, it’s done. There’s no need for post-connection sealing or inspection beyond a visual check that the connector is fully seated. Compared to traditional crimp connectors, which can sometimes be improperly crimped leading to intermittent failures, these auto-electric connectors offer a higher degree of plug-and-play reliability. They definitely perform on par with, and in terms of speed and ease of use, often surpass other specialized automotive connectors I’ve used in the past.
