WRX AVCS preferred switched power source

Recommended Posts

Seems like an obvious thing that I'm just missing, but when wiring in US 2.5L single AVCS solenoids to a WRX Link 7-9 ECU, what's the preferred source for the switched 12V? Just directly from a switched fuse, borrow the hot side of the TGV wiring or something else?

Just a switched 12V supply. Just need to be sure it looses the power when the key is off and is capable of the current required (a few amps)

If you are doing a tgv delete, just use the tgv wiring.  

I have done it that way many times with no ill effects.

Cool, thanks!

So in conclusion, it's sounding like the reason that I wasn't seeing any decisive info on which is preferred is that any dependable switched 12v will work about the same and one should just use whichever is easier in their case.
