Adding a wire? You should be replacing a wire. What year is the
donor engine so I can look it up in the Bentley. BTW, for the
'86 at least, the FP relay part of the fuse panel in the
Bentley is all screwy. It shows a contact from 48/30 to (unlabeled)
which goes to the infamous yellow wire (ground it to pull codes).
Nope, the yellow wire goes to the fuse holder and the other side
goes to ground...
>From what I can see, a BR/G wire goes from ECU pin 21 to fuse box
terminal BS. This is the same for 84-88. There may or may not be
a yellow wire going from ECU pin 31 to fuse box terminal ILa and on
to the check engine light. This is 86 on.

Don't even think of it. It's the ECU's last defence against
ruptured lower wastegate hoses and torn diaphragms.
