ok any chance you could take pictures of the harness ends that plug into the ecu, im thinking they took the two rows on the harness plug and made them 4 rows to consolidate them and save space for printing. Seeing the harness plugs and wire colors would be helpful. If this is the case, then once we figure out how they split them, it should be fairly easy to determine what pins are grounds and what goes where.
Also I thought the Kl47 was a 95 ecu and still obdI? i thought 96+ obdII ecus are named different like the 3rd character is a letter not a number, jsut like the KLK1
