Re: 3-pin Diagnostic Port on P1 Spider?
Hmm just thinking,
On the Fiats (if its the 3 pin connector) they normally came directly off the ECU (must be similiar), so if there is a loose three pin connector somewhere around the ECU area (looks like a loose bit of wiring loom not plugged into anything) that's your boy.
Unfortunately I don't know if the Alfa is the same. I know on pretty much all models of cars when they were converted to OBD II the connector normally emintaes inside the cabin thus easier to locate.
I'd try near the ECU (wherever it is positioned on your car?)
