    07 SN Clarion CDM4a Stereo w/amp won't power on, no power on yellow

    I have basic electric knowledge so bare with me! I turned head unit and amp on using a battery jump so I know they work independently. No volts at all on yellow into head unit and at harness connector behind it. Red has proper 12.6v when accessory is on & trickle when not.. Ground I believe is good for all the connections I have tested. Blue remote lead from head to amp shows continuity. 2 time delayed fuses in battery area, and 1 amp Red inline are good. Did not see a fuse in yellow. No circuit breakers are tripped, but also don't see one for the stereo on the board. Tried to follow yellow back to under dash and to 3 way toggle switch for "All Off"/Standby/"All On"... don't see it. 2 yellow wires there are labeled for other things. Thanks for your time, its appreciated!!
Working...
