Review on 🔌 Waterproof Automotive Electrical Connector Terminals Kit - 708Pcs, 43 Kits, Male & Female Pin, Car Motorcycle Marine Truck Boat by Brent Saake

They are as cheap as you can expect for this price. I personally wouldn't use them in repairs or in wire harnesses because connector tolerances vary: the pins don't fit well in holes and tend to bend when mated, or there is excessive play when mated so there's little hope of an airtight connection Seal. However, they work for my application, make quick and dirty diagnostics when troubleshooting circuits, and have connectors with different pin types. You have to collect several and find the one that fits best.
