98 v8- 12v switched source

Hey Guys
Finishing up my e-fan swap and down to the last wire.
Need a 12v switch/ignition powered source to trigger my relay. Wondering if you guys have any ideas?
Passenger side of the engine bay area would be great. if not... running a wire through the firewall from my aftermarket head unit harness
thanks in advance

Several options in the PDC under the hood next to battery.

Since you are in Cal, I suppose it has Cal emissions?

If not, the connector for the evap pump will be stowed near the purge solenoid. Orange wire is switched ignition.

IIRC cigarette lighter plug only gets power when the ignition is on, could tap off that.
Reliability is relative
