Powered circuits/accessories when using remote start - wideband o2 ins

[khester84]

Hey guys, I'm trying to install a wideband O2 sensor and controller in my 2008 silverado, and have a few questions. The user manual for the wideband says that the wideband system must be powered on any time the engine is running, therefore I need to tap into a power source that is switched on when the remote start system is used. I admit I haven't done a whole lot of research just yet, but I did notice the rearview mirror electronics are active when a remote start is issued, does anyone know what fuse powers the rearview mirror instruments?

 

I want to use an add-a-circuit so I don't have to touch any factory wiring, and I'd also like to keep the aftermarket gauge power wiring inside the cab as well. Thanks!

find an ign fed circuit terminal that is empty and on when the truck is remotly started on the relay center or somewhere ,get a manual online thru alldata $27/yr if required ,

 

taping into mirror for example may max out the circuit IMHO

 

dont forget to fuse the new circuit
