Need wiring help!
 

Hey I just bought a 1985 rx7 yesterday the body is great but... The wiring is a mess. The guy I bought it from said that the kid who previously owned it had touched the + terminal of the battery to the engine bay. It ended up shorting allot of the wires in the engine bay. I am going over all the exposed wires with a soldering iron and some shrink tubing. But I was wondering if you guys could provide some suggestions of what to do after this because I'm kind of lost and don't know how to re organize all these wires. The guy had cut the dividers off the cables to get access to the frayed wires.

Edit: Cant upload the pictures on the form for some reason wont let me. Maybe because I'm still too new but I have them on imgur already so here you guys go if you want to see the mess I have to deal with....

Pretty colors O.O I wish my wires were that clean.

Idk what to tell you but given my knowledge on wiring and electronics outside of cars and the grounding in a car I think I can tell you that there shouldn't be too much wire damage if he touched the positive terminal to the chassis because it all grounds right back to the battery, however it is a great way for the battery to kill itself.
The fuses should all be good if he just touched the terminal as fuses are (usually) all on the power side of things so terminal to chassis would bypass those.
If any of the fuses are blown then grab a wiring diagram, someone on the forum has a link to the fsm stuff in their sig, can't find it now but if you need it I have it all saved on my computer.

Yikes! I'd be tempted to post a wtb ad to see if you can find a used 85 harness, cut it just before the firewall and then solder it in based on wire colour codes. Might cost you a bit more but it'll look much cleaner. You can find wiring diagrams here:

To me it just looks like the ratsnest wiring...there is nothing connected to the solenoids. You might be able to eliminate it depending on what emission laws are in your state.

Edit...nevermind...I just saw the rest of the pics. Take G-man's advice.

turns out most of it was just excess wire!
 

Hey took a close look at it and traced the wires back, turns out the guy who had it before had replaced most of the frayed wires already but just made a mess and left several feet of extra wire for every one he replaced! So I spent my afternoon cutting them down then re soldering them with shorter lengths, there's still a few bare wires that I gotta replace. So now my question is whats a good gauge to use the guy was using 14 or 16 before so I'm prob just gonna stick with that?

Thanks allot G-man this is really going to help me figure out where all these wires are going and what exactly they are doing!

I wouldn't trust any of that wiring. If it where me I'd replace the harness with a factory one and not cut-and-splice.
