Switch Pros SP8100 in a '16+ Where did you connect Blue wire?

Having a heck of a time trying to find a an ignition wire under the hood that is not just tiny data wire. Of course I tried the ones labeled IGN in the box with no luck. and I don't particularly want to run the wire all the way into the cab and splice into the ignition wire under the steering column. Does anyone have the blue wire/ignition wire connected and working properly?

Thanks!

 

I tapped into igniton 1 no 2 in the fuse panel under steering wheel.

Where did you tap your yellow wire?

 

Yellow is tapped into driver side fog light.
Damn, ok so I do have to run blue it into the cab. I was hoping to keep it under the hood.

thanks!
