Continuous Duty Solenoid/Power mirriors

[Cunning193]

I recently replaced my continuous duty solenoid on my 2015 Greyhawk 31fs. The two smaller connections go to a positive "run source " that activates the solenoid while driving to charge both the coach and house battery. Does anyone know what that source is? It doesn't activate unless I press the AUX start switch. I have checked all DC fuses unless there is an inline fuse that I have not located. Also can't find a fuse for the power mirriors. Thanks!
