Very good!

I couldn't find my previous notes on AEB2568 pinout, so last week when I had a spare half hour I manually checked a loom and noted the pinout..

From my notes (my notes lol.. so they probably won't make quite as much sense to other people but I'll understand perfectly if/when I read them again)....

Pinout taken from a late spec King AEB2568 loom (2015ish) with OBD connection wires.

Pins are numbered 1>56.
Pins 1>28 on one row (row A), pins 29>56 on the other row (row B). Row A and row B numbers run in the same direction, thus pin 29 is adjacent to pin 1 and pin 56 is adjacent to pin 28. There is a space between 14 and 15 and there is a space between 42 and 43, I have termed A *tbc below*

When looking at the connector from with the purple slide block at the right, row A is numbered 1 bottom left to 29 bottom right.
When looking at the connector from the front with the slide block at the right, row B is numbered from 1 top left to 29 top right.

When looking at the connector from the rear (wiring side) with the slide block at the right, row A is numbered 1 top left to 28 top right.
When looking at the connector from the rear (wiring side) with the slide block at the right, row B is numbered 29 bottom left to 56 bottom right.

When looking at the ECU face up (label on top) with connector block pointing toward you and slide block at the right, numbering is 1>28 top left to top right, 29>56 bottom left to bottom right.

There is a column space between 14 and 15 and a column space between 42 and 43. I have termed A1>14 block A1, A15>28 block A2, B29>42 block B1, B43>56 block B2. A1 & B1 are together (just different rows) and A2 & B2 are together (just different rows).
