Did you recieve that Pm message? It doesn`t seem like it sent?

I got you pm. You can to select the "sent box" option in advanced settings.

2011 USDm sti. For fail safe I connect the brown and white wires to 33 as well as a wire out to the wastegate solenoid?
Where does the wire tap into the wastegate solenoid?
Do I have to connect the purple wire for gauge dimming?

Re: Subaru STi to HFS-3 wiring diagrams (2004-2011)
 

First you need to cut the wiring from pin33 in two. Connect the white wire to the "one half" from the pin33. Then connect the brown wiring to the other half. If you are not sure what I am trying to say, take a look at the wirng diagram on this thread.

The purple will enable the "dim" trimmer for night driving. It need to be wired to a head lamp (+) side. If you don't mind the gauge led gets too bright at night, leave it unconnected.Tape it up.

I see. 33 is the wastegate solenoid lead. Much less complicated than I was trying to make it.

2011 USDm sti
Currently have jumpers at idc, pwm, fav, prk, dr0, clp, fs0, dhb

I have wired the system per your diagram on page 1 and get a cel when the system is turned off.
Will setting the jumper to dr=1 fix this?
If the jumper is at dr=1 will I get a cel if the system goes to fail safe or will it just go to wastegate pressure?
When the system is turned off is it possible to run a separate non-water injection tune?

Re: Subaru STi to HFS-3 wiring diagrams (2004-2011)
 

DR=1 will fix the cel if the boost is reduced to wastegate pressure.
If you want to run a non-wmi tune, unlink the DHB jumper. This will allow you to run full boost when the system is switched off.

Re: Subaru STi to HFS-3 wiring diagrams (2004-2011)
 

I assume that means I move the jumper from DR=0 to DR=1? Or do I move it from PRK?

When the DHB jumper is unlinked, is that something I will have to do every time I switch to non wmi? Or do I leave it unlinked and when the system is on it will go to fail safe without it?

Do the rest of the jumpers appear to be in the right spaces (idc, pwm, fav, prk, dr0, clp, fs0, dhb)?

Re: Subaru STi to HFS-3 wiring diagrams (2004-2011)
 

Yes, just move the DRO jumper to DR1.

DHB only affects the guage off mode. When you switch the gauge on again , everything is the same as before.

You can always refer to the gold dot on top as factory setting.

Re: Subaru STi to HFS-3 wiring diagrams (2004-2011)
 

So just to be clear if I remove this jumper I do NOT need to reinstall it for the fail safe to work properly while running wmi. All I would need to do is change the tune depending on if the gauge was on or off.
