Hi All,

I am changing the alternator on my car but the new one has different connections. The original has a 3-pin connector ( marked B+ and D+ ) but the new one is different. I assume the B+ (red) wires can both go to the B+ terminal on the new alternator, I am not sure where the blue wire should connect to. The only other marked terminal is W ( warning lamp I guess ), but what is the other terminal in the black plastic area? Could that be D?

Thanks for any help.
