I am new and having an issue navigating thru to see if this has been covered already (I'm sure it has). However anyways I cannot for the life of me find where to install my aftermarket wiring harness in the trunk at the factory amp. I've installed way too many stereos in my lifetime and this is the first time I've been stumped. I looked all over online and still no luck so here I am.
