ECU Connectors

ECU connectors are typically proprietary to a manufacturer, and therefore you won't find them called out in the standard product listings. Many times you're not allowed to even order them, and when you are, minimum deliveries of 1k+ units are expected.

Prove me wrong, though, as I would love to get a hold of some ECU plugs in small quantities. Your best bet is to befriend a tech at a place that manufactures replacement ECUs and see if they will send you one for the cost of a few beers... or you could go to a junkyard and find an old ECU to desolder it from.

Macgyvers2000 is correct. The automotive company would have had a custom or semi-custom connector shell made by the connector company (Amp in this case). The crimp pins may be a standard crimp pin for that company. However, for a 94 Toyota Supra, the ECU and harness would have been made by AMP in the far east.

At around the same year of your Supra, I was working on a project where I was needing connector shells to mate with gauges and harnesses made by Amp in the far east. In this case, it was to mate with outboard motors made by a particular engine manufacturer in Japan. Since my need was for several thousand, I was able to work with the AMP sales person. As I recall, this was somewhat unusual, in that for Amp, the connectors in the far east were a completely different business unit of the company. I did eventually did get samples and drawings, but all in Japanese. The project never made it through development, so no volume was ever ordered. Or was it Molex???-don't exactly recall now.

Today, Amp is owned by Tyco. If you need more than just a few connectors, see if your ECU has a connector in common with some very popular car model of the performance market. I would then investigate after-market ECU manufacturers who make ECUs for engine modifications, turbos, etc. They would have found a source of the connectors to produce their ECUs to mate with the standard harness. In this case, there might even be companies that produce after market harnesses for those who modify their cars.
