2014 Entune Audio Plus to 2012 Conversion Questions

Hi Everyone,
I have two questions for the TW people. I have the 2014 HU in hand and started the install but ran into two problem.

1 - The exhaust fan is damaged and makes noise. I was able to remove it and it is a Panasonic fan. Here are the numbers on it: EDQF4GH52 DC4.5V 0.04A 3727L2. Does anyone have an idea where I could get a replacement? I have tried my google-foo, but not getting much love.

2 -I discovered that my OE USB port isn't working with the new HU. Now, the one cable that doesn't have a home is a blue plug, and it doesn't fit anywhere else. Does anyone have a solution to maintain the OE USB port usage? I found numerous threads on here with DIY solutions, but I could swear that there was a way to make it work. I have found the two following adapters, which may make it work. Does anyone have any experience?
