The GTO (Great Turn On) on my DM-810 is staying awake which is keeping the amps awake. I re-pined the 810 to ignore the GTO but now I need a positive that comes on with ignition. I've probed most of the stuff in the spare tire well and it all seems to be hot even with Jag asleep. Looked at the infotainment PDF provided by others and it looks like the Green lead at the amp may be switched. It's labeled RBD power. What have you guys found to use for your aftermarket add-ons?

 

I have not needed anything in the back area, but the one indicated here is ignition. Used it to activate my Methanol injection. I am sure there are others...but this one is switched for certain.

Your suggestion prompted me to look at the Jag manual for fuse box locations and fuse descriptions. The one you grabbed is the exhaust button. Nothing wrong with that but I figured I could find something closer to the way-back.
Wound up on the power seat fuse which is under the helm. Works great.
