    Hi All,
    I am about to fit an exhaust valve remote actuator to my F430. Anyone know where I could pick up/splice a 12v supply from behind the rear engine side panels ideally. Maybe the existing solenoids have a constant ignition 12v?

    Any help greatly appreciated.

    Was thinking the right side looking from the rear as there is no canister in that side.
    Regards
    Tony.

    The RH exhaust valve power supply (Fuse PDF12) also feeds a lot of other devices (via splices):

    MAF
    Secondary Air Valve
    ON/OFF valve (intake tract tuning)
    Aircon compressor relay coil

    Does the exhaust valve remote controller also have to power two solenoids valves of its own?

    Whilst the main wire coming from the fuse to the splices is 1.5mm^2, the RH controller wire size is 0.5mm^2.

    Splice location unknown.

    What a fantastic answer, Qavion. Thanks for that. I saw online that they looked too thin. So is there a 1.5 that you can think of any place in the side pods I could use. Happy to inline fuse it as extra protection if the fused amount on the original is too high. A 5amp will be sufficient for this air pump, I imagine.

    There is nothing I can think of at the moment. Unfortunately, there is a serious lack of key power in the engine bay. Nothing needs it. Even that PDF12 fuse is controlled by the RH Motronic ECU rather than directly by the key (but the ECU is responding to the application of key power)

    Does the controller paperwork mention power requirements?

    It does not, unfortunately. I guess I will have to just see what I can find when I open the sides up. I can run it with an amp meter inline to see the draw. I don't expect it to be too much. Mostly it won't do anything as the valves will be open for 95% of the time.

    I had mine installed yesterday, two hours total to get a nice neat job done. The mechanic pointed out that removing the liner was what took the longest.
    I’ve been driving around with the valves open and it is definitely a head turner sound especially when in manual mode!

    Brilliant, I can't wait to do mine. Friend coming round on Monday to help (as I've done my back in and dare not lean forward!) Mine is a cheap ebay style generic device but fingers crossed it will do the job just fine. Looks well made and generates a good vacuum, it seems.

    As mine does not use the existing harness I just need to find a 12v back there I can splice power from.

    Do you know which side its mounted or was yours both sides? Mine is one unit and a T piece in the hose.
