Blitz fuel controller wiring questions

[Toy_Yoda]

Need help with an install of a Blitz supercharger on a 2006 Scion Xb. Blitz's online instructions appear to be for the 2004 and 2005 only. Also the fuel control box has 9 wires and the instruction show it as only 8. Seems that my fuel control box has a light green wire not shown in the instructions. Can anyone clue me to what function each of the 9 wires controls so I can attach them to the ECU in the correct location for the 2006. You Yaris guys are the most knowledgeable when it comes to 1NZ-FE performance info. Thanks.

Can you post pics of what you have? Does the fuel controller have the 8 pin connector with an second wire in one of the 8 positions?

Also, the instructions for 04-05 should be fine for your 06, as 04-06 all used the same ECM configuration.

The connector has 12 spaces for contacts but only uses 9. Top row is the same as shown on the instruction but starting with two vacant places followed by pink, red, yellow and then orange. Second row has one vacant space followed by the extra light green wire not shown in the instructions, the dark green, the black, the blue, and then the white wire. I also got a spare fuel control unit when I bought the Blitz used and it's wired identical to the first.
