I wonder where I got that?

OK, now I know. The wiring diagram in the 87 electrical manual is different than the diagram in the fuel system section. The fuel system section matches the one in your last post, and on checking, is correct. The ignition system diagram in the electrical book also has a 14pole connector shown for the b38, but the only wires in question are the 1.25B battery hot wire and the blue ign on wire, which are covered in the 10pole post.

Wire like the 10pole as shown. I'll edit my erroneous post above.

Good catch.
