03 Y61 TB48 Throttle Body issues / part number and couple of questions

[StavTB48]

Hi mate, just had a look at mine.

bank 2 (closet to firewall) connects to the connector with the green/yellow wire.
bank 1 (closet to radiator) connects to the connector with the blue/ red wire.

hope this helps.

Thanks mate this confirms that my looms where plugged in backwards, not good considering Ive been driving the car everyday racking the k's up like it since I purchased the car... wonder if this could have shortened the life of the sensors or even worse what else this could have done.

ve had to stop playing with it today will have to get back onto it tomorrow. Do appreciate it a lot!
