hi all, i have just got a new alternator off the net as my old 1 was giving up on me. Its shaped exactly the same so it will fit, the only thing is the electrical side of things is a bit different. ive put a pic of the 2 below to show what i mean. the original i just took off just had 2 wires on the alternator. the new 1 has 2 parts where wires are too be fitted too, as shown in the pic circled in green, but i am worried about the spade connections found which i have circled in red, am i missing something or are these nothing to worry about and should i wire it up as the old 1 was?!?!

the old alternator says b+ and d+ for the wires and the new 1 says W and B.

any help on wiring this would be great cheers.
