1990 300ZX Factory Radio Wiring Diagram

[Nissan300Zfor2]

I have a 1990 300ZX 2-Seater with the BOSE System. I recently took out the entire system, but left the wiring in the dash. I need to know if someone can tell me how I can identify the wiring to use the existing wire harness for my new speakers. I also need to know when installing my aftermarket CD-Player which is my ground wire within that harness. If someone has a wire diagram for me to identify what is what, would be appreciated. PLEASE HELP! Thanks in advance!

ok i have downloaded and printed the audio and power antenna diagram

now i am wondering how to read it and make sense of the big wired mess in my dash.

fyi i just bought my z and no factory plugs still exsist for the audio just shielded wires and other non shielded wires. this is kind of a big undertaking so any help would be great.

the diagram is also hard to read not sure if some of these are B/R or B/A? not sure why some of them have / and some don't. there is no key to make sense of this thing.

a very frustrated new owner.

thanks guys.

most times the slash denotes the color of the stripe on the wire insulation. If you can't get the wiring diagram sorted out you could always take it to someone. It may cost you some money but it may save you from planting a screwdriver in your dash....

Well, if nissan300zxfor2 would get on and check this out to let us know how it helped him so much that would be cheaper. I still haven't figured out these wiring diagrams. I haven't gone into them in detail, but still haven't figured them out.
