What connector type is this on aerobic septic system control board?

[DaveWW00]

I am connecting a zwave sensor to the control board of my septic system to notify me when alarm goes off. There is an external horn connector on the circuit board that i have pushed wires into and got working with the zwave alarm but for better connection i need to find the right connector to use. Its a 2 pin connection. I've searched and searched online for connector that looks like it will fit and went through all the manuals and things for system but they dont say anything. Below are images of the connector. Any help would be appreciated. Thanks!

Frankly I would just desolder that connector and put one on that you can find the mate for. They're around 25 cents each for the more common/simple designs. This can't be high current so primarily you just need to worry about maximum allowable pin size (the size of the hole in the PCB) and pin spacing, then head somewhere like Digikey and input those parameters to search for them.

For example if your pin spacing aka "Pitch - Mating" is 0.156" (3.96mm), you might pick something like the following:
https://www.digikey.com/product-detail/en/molex-llc/0009652028/WM18823-ND/1220238

Then of course you'd need the mating female connector, which is linked at the bottom of that page and is here:
https://www.digikey.com/product-detail/en/molex-llc/0009501021/WM18813-ND/1220229

AND don't forget to buy the pin contacts that go in it! You'd need a couple of these, linked at the bottom of the female connector page under "Associated Product":
https://www.digikey.com/product-detail/en/molex-llc/0008701031/WM18820CT-ND/1220245

Remember, these only work if you have 3.96mm pin spacing ("Pitch - Mating" on Digikey). If it's something else you'll need to start over, maybe one of the following then get the mating other piece and the contacts for it as above, linked from their respective pages:

Hard to tell from pictures, but those look like standard wire-wrap post pins. If so, you might be able to find and disassemble a circuit board IC socket that has compatible-sized female socket receptacles. There are also pre-made jumpers available that mate with wire-wrap pins, so you could easily make a "connector" from a pair of those jumpers. Beauty and neatness and the ability to mate and un-mate the connection frequently do not appear to be requirements, so you might want to explore this avenue first before committing to something else.

Thanks.

Unfortunately, I can't make any mods to board itself since it's inspected annually by county and based on stupid little things they have failed me for before I don't want to risk it. Also very hard part to access and don't want to risk breaking something especially since it's expensive to replace.

Take a look at this connector from Molex. Looks Like the right one.
