ES Automotive Connector Test Kit 146 Silver — 54-piece set with 48" stacking banana leads in rugged compact case

This compact, organized kit gathers 14 terminal adapter sizes, stacking banana plug test leads, and storage in a rugged 12.5" x 9.5" x 1.75" case to speed connector-level troubleshooting on domestic and foreign cars. The selection of flat and round terminal adapters lets you reach hard-to-access pins and probe harnesses without damaging connectors, while the 48" banana plug leads bridge test meters and scopes cleanly. ES designed the kit to maximize coverage and reduce the time technicians spend fabricating makeshift leads.

How does this kit connect to my multimeter or oscilloscope?

The ES 146 uses 48" stacking banana plug test leads that plug directly into most DMMs and scopes. Stacking banana plugs allow multiple connections and safe daisy-chaining for simultaneous measurements.

• 48-inch stacking banana plug leads included for long reach
• Banana plugs compatible with standard DMM and oscilloscope inputs
• Adapters terminate into banana plugs for straightforward meter hookup
• Insulated leads reduce short risk when working in tight engine bays

Which vehicle connectors and terminal sizes are covered?

The kit supplies adapters for 14 different terminal sizes in both flat and round profiles, covering a broad range of domestic and import automotive connectors. This variety helps you mate to factory pins without forcing or altering the original terminals.

• 14 terminal adapter sizes for common automotive pins
• Includes both flat blade and round pin adapters for varied harnesses
• Works on sensors, ECU connectors, lamp sockets, and wiring harnesses
• Stored in a compact case for quick access on the job

Will the kit speed up diagnostic work in the shop or roadside?

Yes—having pre-made terminal adapters and long leads reduces time spent on improvised wiring and repeat connections. Quick matching of the correct adapter means fewer damaged pins and faster testing cycles.

• Pre-sized adapters eliminate time-consuming adapter fabrication
• Stacking plugs let you measure multiple points without rewiring
• Durable case keeps components organized for efficient workflow
• Designed for repeat use in shop and field environments

What’s included and how is the kit organized?

The kit comes as a 54-piece set inside a shallow, labeled case sized 12.5" x 9.5" x 1.75", making it portable and easy to stow in a toolbox or service vehicle. Pieces are arranged for quick identification so you can select the correct adapter at a glance.

• 54 pieces total: terminal adapters plus 48" stacking banana plug test leads
• Compact, low-profile case for bench or carriage storage
• Adapters sorted by size and shape for fast selection
• Suitable for repeat connections without damaging factory pins

Who this is for: The ES 146 Silver test kit is suited for professional mechanics, electrical technicians, mobile service providers, and serious DIYers who need reliable, connector-friendly test methods. If you regularly diagnose sensors, harness faults, or ECU connections on both foreign and domestic vehicles, this kit reduces guesswork and protects factory terminals while speeding up measurement tasks.
