top 1 is too the actuator
middle 1 to compressor housing
bottom 1 to the meter head

thats how it is on mine neways, it was wrong when i 1st got it

i have a question tho, what if you have 2 nipples on the comp housing?? (1 in normal place and another on the 'out' outlet), 1 of my turbo's has that and im unsure so havent fitted it
