- for the wastegate
- ecu
- and before the throttle body
but i couldnt tell u for sure which way they fit to the boost solinoid
but at a guess looking from the right side of the engine left nipple would be to the before throttle body position
top nipple to the ecu
right nipple to the wastegate

From memory, the rear connector heads down to the wastegate, the bottom one goes to the throttle body and the front to the non-charged section of pipework just after the air filter
WOO! Servicebox agrees with me

hi, mjb if the none charged air and the throtle body pipes were the wrong way around would that give intermitent boost and when it does boost it gets over 1bar ?
