I'm looking for a replacement male connector to fit this coolant level sensor from a 1989 VW Jetta. Finding replacement sensors is straightforward, but what does one do when repairing a missing connector?
In addition to the suggestions in comments:
Let's say that disaster strikes and not a single usable connector remains in the world.
You can still wire up or solder something as simple as this. You will need to figure out the polarity to understand which wire goes to which terminal and ensure that the two wires cannot cross one another.
The best option for an exact match seems to be a salvage yard, at least so far.
However, I was recently looking for a replacement connector for the coolant temperature sensor and noticed that the connector looks very similar to the coolant level sensor, so I ordered two. It's not an exact fit as the retaining mechanism doesn't click securely into place, but it's a solid electrical connection and more robust than two spade terminals.
