Stereo wiring help please!

I am working on wiring up my stereo and am having some difficulties determining the correct wiring for my harness. I am typically pretty good at this type of stuff but this documentation has me stumped.
Here is what I am working with:

2010 40th with Bose
Scosche NN04B harness
PAC SOEM-4 LOC
Pioneer AVH-P3300BT Head Unit
Axxess ASWC
Relay for parking brake bypass

The part I am having trouble with is that the Scosche directions suck. Their packaging says there is a blue/white wire for remote amp power which I would expect. However on the harness itself there is no blue/white wire. However it does include an orange/black wire that is marked “dimmer ground”. This is not indicated on the package at all.

So I have no idea where to connect the remote amp wire from the PAC SOEM-4 to the wiring harness since there is no blue/white wire on the Scosche. Also, what the heck is the orange/black wire for? The head unit only has one illumination/dimmer wire and it is orange/white just like the other dimmer wire on the harness.

Here are pics of what I am talking about. Any help would be appreciated. If no one has any ideas then I suppose I will contact Scosche but I thought I would try here first. Thanks
