In the pic from left to right: (with reference to Kdog's wiring diagrams)
brown - Earth (E2) - pin 9
blue/red - VC - 5V for sensors Pin 1 on 16 pin plug
yellow/black - ICS - Air flow meter output Pin 2 on 16 pin plug
light green - THA - air temp sensor - Pin 3 on 16 pin plug
brown - Earth engine
could realistically bond browns together, but I could be wrong.
