Just replaced ignition leads & my manual doesn't show which 3 colour coded vacuum / air lines connects to which Throttle Body connection (stamped A, E & P).
The 3 lines have yellow, green & red tracers.
It looks like yellow connects to A, but I would be greatful if someone could confirm this.

Had a look at the TL and the vacuum hoses are as follows:
Yellow A
Green E
Red P

I have a 2000 TH sports and my lines are yellow, green and blue. I assume that the blue one goes on P, is this correct?
I have 1999 TH Altera and yellow goes to A, green to E and red to P.

Thanks i286 - good to see it is same as later 6G74 in the TL. ( note for ARS55: I have blue line(s), but not directly connecting to the TB)

Yeah I'm wondering about mine as it looks as though my red line may have been changed to generic hose at some stage.

I can confirm that is its from front to rear
Red
Green
Yellow
If it is not in that order it has been put back wrongly at some stage and should be corrected

So where does the blue line run?
Blue line connects fuel pressure regulator with plenum (just after the throtle body). Yellow and green go to EGR selenoid valve and red goes on Purge control selenoid valve.
