72RSbug Posted September 7, 2009 Share Posted September 7, 2009 I need to find out where to connect the 2 wires coming from the stock boost controller (primary side) to the ECU My wiring loom that came with the engine doesn't have the connector for this boost controller. http://memimage.cardomain.com/ride_images/1/3378/2641/8443820225_large.jpg A3 on my ECU (Wastegate booste duty solenoid) wasn't attached to anything. Can anybody confirm that this has to go to the primary boost controller? Engine is a 1996 EJ20R (TT) by the way with a 3 plug ECU marked (4G) Link to comment Share on other sites More sharing options...
