I found a website that lists many of the old YPC connectors for sale. Here's a link to their YPC inventory: https://www.hi-1000ec.com/product-list?keyword=ypc&Submit=Search&page=1

The last item in the search is for a pin removal tool, too.

The website whois shows a registration in Japan. I placed an order last night, and today I received an email with a photo of the shipping label and a photo of the parts I ordered bagged up. That certainly inspires confidence in ordering. This should help in making repairs and modifications to 260Zs and 280Zs.

I'd like to add that with the male 6-pin waterproof connectors would work for jumpering out the voltage regulator on a 280Z. It's too bad the 260Z uses a different connector.

Well, that was fast. The connecters arrived a little while ago, and I have put them in a divided storage container so they will be ready to use.

If you need YPC connectors, hi-1000ec.com is legitimate.

I purchased extra male 3-pin and 6-pin waterproof connectors. The 3-pin is for wiring a conventional Bosch relay for the AC relay. The 6-pin is for jumpering out the voltage regulator connectors in 75-77 280Zs when converting them to internally regulated alternators.

I bought connectors that could be used for the center gauges, too. It could also come in handy for a conversion to Speedhut gauges.
