MGB: Bosch alternator conversion

I've got an early 78 B with a rebuilt Lucas alternator (3rd time) and want to convert to the 78-80 Bosch Fiesta unit. The wiring harness plug to my Lucas has three blades (small, big, small), while the blade configuration on the Bosch is: big, big, small.

How do I adapt the harness to the Bosch alternator? Thanks !

I had to convert my '71 from the 5-wire to the 3-wire plug when I installed the Bosch alternator, it's pretty easy. Look at this from Moss Motors:

Thanks for the quick response and link. I printed the photos and diagrams and will compare them to the harness tomorrow. G

John, thanks for the quick response and link. The connector shown on the Moss data sheet looks exactly what I need to interface the existing harness to the Bosch alternator.

Follow Bob's instructions in Lee's link. DIY, save a few $, its not hard.
