Bose Sub Swap

A

So I have an 05 FX35 and my subwoofer has the electro magnetic relay issue, part#28170 CG000. If I smack it it will work but when loaded with cargo it’s hard to do that. I have acquired a sub from a QX50 part #28170 4BA0A. I have the wiring summary for the 05 sub and I just can’t find the newer subs information to splice the wires. If anyone can help me understand what wires to splice together that would be amazing. I can assume the large Blacks splice and large purple goes to the red/green.

I have no experience on the QX50, but I have two first gen FX subs if that help seating around. If interested message me.

I know this thread is old, but did you ever find out the wiring to the factory sub? Does anyone know the wiring assignment for the Bose sub?
 
I ended up blowing the fuse that runs most of the accessories, I can’t remember which wires went to where but I have it hooked up and running good now I used a multi meter to fiddle with it and trial and error

so are the wire assignments the following? :
black wire = ground
Purple = red/green = 12V+, battery
pink = remote wire
black = speaker +
white = speaker -
