14 pole connector in two rows of 7, catch up, numbered l-r

1. Y yellow
2. BY black yellow stripe - ground
3. B black - battery +
4. L blue - Ign on 12v+
5. not used
6. RB red black stripe - battery + add 15a inline fuse
7. not used
8. LgB light green black stripe - wire to speedo reed switch
9. YG yellow green stripe - not used (fake boost pressure)
10. not used
11. BY black yellow stripe - ground
12. BR black red stripe - add jumper wire to read trouble codes.

14. not used

EDIT: ALL THE ABOVE IS WRONG. SEE BELOW.

The spark box has a couple of connections thru the b38, but they are covered in the above, using the 87 spark box.

One test you have not reported on. On the dizzy harness connector, there are 3 wires, white, black, and black/yellow. With a voltmeter set on the lowest range you have, connect the leads to the white and black, and spin the dizzy by hand. You should see (using dc volts) a small value varying above and below zero, which is the a/c voltage the dizzy generates as it turns. [color:"red"] [/color] [color:"red"] [/color]
