If it's anything like the AX of the period fitted with Bosch injection then it'll be the connector nearest to and part of the Injection ECU wiring harness.

May I ask the reason why you wish to read the codes?

On a 32 year old car loads of wiring connectors can be a poor, especially earths.Best have a look at everything with a can of electrical cleaner, including the main earth that bolts on the top of the gearbox. There are not many multi plugs on those old 205’s.
It’s a very long time since I worked on the mono injection TU engine. There is a large multi plug that fits on the mono unit. Pull it off and clean it all up. I think there is a couple of small ones as well.
You would be better off with diagnostics, if you could find an old school Peugeot/Citroen specialist who still has the old Peugeot Diag kit.
