In my personal experience, 99% of car audio installers do not know or do not have the time to care about proper wiring.
From the sound of everything, I recommend that you remove everything that was not the original factory wiring. You need to return everything back to stock so you have a baseline to work with.
The purpose of the fuse block is to prevent excessive current draw, such as shorts or malfunctions, from burning down the car. The fuse would blow when the max current is exceeded instead of continually feeding current and overheating the wire.
You need to remove all non-factory wires because I would imagine that they are garbage. You need to then repair the original factory wire harness so you know what's going on with the wires.
I recommend borrowing a friend's stock Nissan radio and plugging into your car and check all radio functionality and speakers for proper functionality.

My old radio doesnt have this wire so I'm not sure where I should hook this one up to. Any suggestions?

You need to get the instructions manual from JVC. They will tell you what wires do what. You need to do your homework before asking anyone else. I found this on JVC's site:

It looks organe with white stripe is for the car illumination control. I don't know what colour this is on the S14 off the top of my head.
There are 1,000 ways to install a radio. About 980 of those ways are wrong.
The easiest way is to get a Metra miracle harness for the headunit and the car. Plug and play. No guesswork.
