I have read all over the SVX forums and found that I can ground pin A4 at the TCU to get Power Mode full time... or put in a switch for on/off.

  So I tried this last year, and it did not work.   I just got a poor running SVX with check engine light.

I double checked the pin, yes it is A4, yes it is the TCU.  What I found was that there was some voltage on that pin.   It would lightly spark when I touched it to ground.

  Does anyone here have any experience with their SVX?    I have heard this is similar on the late 90's Outbacks and/or Legacys.    Any help would be appreciated.   Thanks in advance.
