12 volt switched source in engine bay?

[Okki]

I'm looking for an easy place to tie into a 12 volt accessory switched wire in the engine bay (i.e. only powered when the car is in accessory or running). Can someone who has done this before please let me know where they tied into?

Thanks!

On a side note, the Stinger SGP38 high voltage relay fits brilliantly on the driver side using factory mounting holes. Is an 80amp relay.
