What Does Trigger and Accessory Wire for Installing Stereo Head Unit Wire To

Question:

Hello! I am swapping out my older awm970 for a newer JWM60A. Many of the wires convert over easily but I have two wires left over and don’t know where they get connected! Yikes! Out of the plug that I cut off the older unit it has a pink wire labeled trigger and a yellow wire labeled as the accessory power and has a 15amp fuse in line. My question is what do I connect them to on my newer units wiring harness? There is not a yellow wire on the new unit to plug into and the only pink wires on the new unit go to speakers... help! This is going in a 2013 Winnebago Era 170A

The trigger wire would be for activating an external amp. Basically it tells the amp the stereo is on and it should turn on too. The accessory wire is what triggers the stereo to turn on when your ignition key is in the "accessory" position.
