HelloCould someone please advise which way the arrow should point- to the pipe connected to the top of the spider or to the one that goes to the throttle? TIA

 

Don’t think it matters, it’s a simple on/off air valve but arrows normally show flow direction so I’d point it toward the throttle body.

 

​​​​​​Thanks. Needs to be oriented correctly as it increases idle speed when ac is turned on by changing the fuel /air mix. To your point though makes sense for arrow to point towards throttle which is what I ended up doing.
