Random mystery plug... can you identify it?
 

Hello all,

OK, I never thought I would own a Jaguar but then again I was never put off by the thought. In a recent group of trades that I have done I have aquired a 1990 XJS Convertible (seen in my picture). She is absolutely beautiful and a true pleasure to drive. Now, I am a bit anal about making sure that cars that I but or trade for are as complete and put together as possible. Since I know squat about Jaguars I thought I would throw this into your corner for help in identifying the random mystery plug that lays dormant behind my master cylinder assembly. Could it be a service diagnostic port? Am I missing a component that should be mounted there? I have no clue. Can anyone here help? It looks like a trailer lighting plug... it is for (god forbid) towing behind a motorhome? Any help would be appreciated.

I have no clue. But since your user name is sharkbite I thought you would appreciate this. The porpoise will assist you to the shore, your prosperity is their reward. The shark sees you as opportunity or sport. I have no doubt that your question will be answered here.

Thats the connector for pdu(portable diagnostic unit) that is so old and most that have them dont work correctly anymore and soooosloooowwwww
its not even funny. But back in the day it was state of the art to diagnose problems with. You just pull off the protective dummy cover and plug in the pdu's connector to talk to the car
