Hi!

I'm assembling the wiring on the 16V engine. I've managed to find out what are all the connectors used for except the three connectors shown on the image (two connencors and the short-circuited one) and the relay. The harness is from the non cat car since the pin for the lambda probe signal is missing on the harness connector.

So if anyone knows....

Thanks!

From top of my mind.
White connector in mid is same as Alfa tester conenctor, you connect testing device there that tells you error codes ECU has.
Take a look at

Yellow if it is relay I dont remember, but I think t is not relay. It probably has only shape of it and inside are only shored pins. It is "jumper" that tells ECU which fuel you re running on, so it can adjust timing/ignition spark.

I've checked the page. I've figured out those two diag connectors. As for the ignition advance, there is a table on that page. It says: yellow relay -> 95 octane fuel -> with lambda probe. But my harness doesn't have a lambda probe. Then there is pin 85 and pin 86 witch are supposed to be shortened with pin 87. I'll have to check that.

But I still don't know what does that red conector do (the shorted one).

Thanks!
