Air Regulator / Idle Question

Yes old-post but for those searching the forums, 

 

similar issues with series 1 RB 25 DET with stock intake and stock ECU in a 73 Datsun 240z.

 

my solution

 

Air regulator power does not come from ECU , raises idle when cold , not ECU controlled .

 

Chris's guide does cover it . 

 

Air regulator valve needs 12v , connects to 6 pin grey connector next to water temp sensor , wire color light blue  the aqua wires are for knock sensor's

 

my wire in was found under intake close to wire for knock sensor . ( was not connected, i suppose in Ca was not essential - but car ran poorly on start up )

 

hope this helps someone, ,
