Yeah, it was never going to fit without modifying the plug to allow the tab to slide in. I think I may have pushed the tab out of place while trying to force it in, but it is working as is for me. I feel a little better the pros couldn't get it to work also, but also disappointed that there isn't a better solution.He played around with the Axxess harness for a good 45min before he gave up saying it feels like he might break something if he forces it in any further.
I used similar wiring(18/9) to get the line out/speaker wires to the trunk and back(previous post pictures). I still need to figure out where the center channel is on the grey plug(wire tap terminals arrived today).Had to purchase 2 things of speed wire ($60 total ) and he just wired it up old school.
