according to ut_evox

"You're going to blow your ECU like that. What you want is a SPDT relay that can be wired to be normally closed and then open when ground or 12V is applied. I'd prefer the grounded approach from a purely EE perspective - it's more failsafe that way if the wire grounds to chassis you're going to lose boost instead of NOT losing boost and popping the gauge circuits if it's setup as a +12V and grounds to chassis."

"So in the diagram I posted, you would want to probably interface with the primary/reactive boost 2-port solenoid (the brown one). Remember solenoids have no polarity - just like injectors which are solenoids of sorts - so it doesn't matter which wire of the 2 you pick for the wiring modifications, but you do want to probably target the ECU side one and not the +12 V constant line.

In the diagram, the EBC side is the ECU side, and everything else would be the same. "
