Got some ideahs and want some help

Hey, I was the one with the head problem, I'm waiting on some parts so i can get that fixed. I've recently put new speakers in and made two sub boxes that fit 6.5" subs in them. very small so you cant see them and you can still put the seats far back. I've been prepping the engine bay for when i get my head. I've been painting some sheilds, airintake, and removing some small rust on the right wall. I also painted that black. So all i need are some parts to get this car up and running. The big problem was overheating. The radiator fan wasnt working. Changed all sensors and switches and fuses before finding out it was the motor. The power still doesent work to the motor because we tested it with other electonics. And also there was nothing when rubbing wires together(positve and negative).
So i'm going to wire my own switch in and own wiring from battery to fan. I was wondering if this was a good ideah. Its really my only choice. I'm thinking of running a 10G wire from battery to fuse to fan. And having ground to the switch. Will this work having the ground relay it? I think it will but not sure... Or should i have positive running through the switch. I'm thinking if it was the posative there would be some sparks when turning on and sparks are bad . But not sure.. What do you guys say about this?
and is 10G wire good?

I have some plans of making my 84 se a fastback version and putting my own custom taillights in. I want to have the cooler looking front bumper installed soon. My interior is nice and nothing needs to be done to it exept i need a nice head unit. I want to get all new suspension parts or some and lower it some. Mabye new rims and low pro tires.. Exhaust will be all new after engine and head fixed. And in my future (couple years) i hope to put a v6 in it. 3.4 from camaro i think. So if you guys can help me with my electricle or anything about my projects i will be getting into it would be nice. I need all the help i can get only being 15 with minimum experience and terrible spelling<< .. Haha thanks

Sounds like the problem is your fan relay. It's in front of the left headlight assembly. I had one that had a burnt up power terminal but was still giving a voltage reading at the connector; it just couldn't carry any current..
