1 - Switched 12V
2 - MPIX ground
3 - RPM
4 - Knock
5 - 12V fused (fuse 24)
6 - n/a
7 - n/a
8 - n/a
9 - Hall
10 - K data
11 - Check engine
12 - L data

Pins 1 and 2 are both at the end by the plastic alignment pin. Its numbered like a race grid, i.e. first row: 1 2 second row: 3 4 etc.

No, just the listed pinout in my quick reference folder.

Colours can be found on page 97-301 in the 88 wiring diagram, the plug is at coordinate O,82

Pin 10 and 12 were inverted ????

And the color is not the same on my car - all white cables are in fact brown !!!

Thanks for your help. Now my SharkTuner is working ....

That's great! Now get out there and start ripping up the ice!

But do you mean "brown" as in "previously were white" or really brown? I thought the factory was pretty careful about reserving "brown" for ground wires...
