Had the bung welded in drivers side, just before the cat.

Innovate recommends power connection to be an "isolated switched 12V source. Circuits that share power with the vehicle’s stereo, ignition system,ECU, lighting, or fuel pump should not be used. "

Having said that-- anyone know of an easy place under hood / behind dash to grab switched pwr. from?

 

Having the same issue right now. About to go take a stab at it later today but hopefully someone can chime in with some help or a wiring diagram.

 

I ended up making my own circuit using a SPDT 30A relay and wiring it off the ECU switched power and ground terminals.
