According to the ECCS diagram from the FSM i have:http://i68.photobucket.com/alb...m.gif

There are 2 "Pressure Regulator Control Solenoid Valve"s (plugs F29 and E48). They are not marked or mentioned in the loom layout pages (the ones that show where the different plugs, sensors, etc. are). Both end up going to the same pin on the ECU, so I can figure where I need to wire that in, but where is the Butterfly Valve Soldenoid (Power Valve Solenoid as per the kn13 EXA/Pulsar NX manuals)?

We have a thread in the FAQ that covers just about anything that you would want to know about the butterfly system on the RWD CA.

Thanks for the reply, but looking that over again I still don't see the info I'm looking for. I may very well have just passed over it, but I am looking for where the butterfly solenoid connects to the ECU. I have the complete setup from my EXA with a CA16 (vac tank, check/delay valves, solenoid) but I am trying to figure out which pin on the ECU controls that solenoid.

Yea, it's easily missed. I had to go over it a couple of times to make sure it was in there. I was pretty sure it wasn't I couldn't find it right off the bat.
