Been on the Greddy site for instructions on the ProfecB and what I can make out is that if you tee both actuator pipes together and run the tail of this to "com" on the solenoid that should be o.k.

Then take a pipe from the boost side of things[ie balance bar]and run this to the control box. Now the querie,can I simply take the electrical connectors off the original solenoidsand if so do I have to remove/replace any pipes connected to them or simply plug them up?

Cheers! ;)

Just disconnect the solenoids and leave the plugs off.

You don't want the pressure signal off the balance bar, it should be off the hard pipe leading to the throttle bodies (ie at compressor outlet pressure, not manifold pressure).

Yeah T the lines together, also tee the feeds together for the other port on the solenoid. Take your boost sender pickup from the balance bar at the back on the right hand side (feed for the stock boost sender). Just disconnect the stock boost solenoid connectors, nothing more nothing less :)

Cheers Andy,and of course JD!-sounded too easy so I thought I had better ask the experts!! :bow:
