91 240 manual fastback issues-wiring, clutch, antenna, etc.

[chivalrybk]

I'm brand new to this but, I am having issues with my wiring. I thought it'd be a good idea to learn about my car by working on it and fixing it up and I'm seriously confused. I'm basically a broke college student trying to fix some of my stuff up. Does anyone have diagrams for a '91 240sx? I just got in some new speakers, antenna, and dynamat. I've removed almost all of interior panelling from the doors back. How might I go about replacing most of my wiring for the car? I also have to replace my clutch and rebuild my transmission. Any suggestions of a clutch to get? I have everything stock except a K&N air filter.

Any (practical) suggestions would be greatly appreciated Thanks
