problem with warning lights at startup

It's the round one indicated by the left arrow.

well.... the last time it was unplugged is on the assembly line in 1988... any tip to remove the connector without destroying everything around?

If you haven't already, remove the coolant reservoir by first unplugging the blue float sensor connector and then pull the reservoir straight up. After that you'll have a little more space to grasp the alt connector with both hands and pull and wiggle. I usually hold the lock tab back with my thumb while grasping the connector in my fist. If you can't get that one loose you can unplug the harness at the alternator itself and do the test from that end. I did my test from the upper connector to eliminate the possibility of interference by the common problems with the alternator harness.
