Question About Turn Signal? and a few more small Qs!

Ok last week I was installing my new headunit. I did everything as best I could, got both wiring harnesses and connected them, soldering the wires and then electrical taping them. Everything was fine, worked great. But what I noticed is it kept shorting out. I was figuring it was overheating as it was getting very hot at the back. I did some research and found out that it was supposed to be getting very hot, the rear was called a "heat dump" or something like that, it is supposed to be drawing out the heat from the head unit. So when I first got it I was messing around with it while it was on and the car was on and all of a sudden it shorts out and my dash lights go out. Then I notice the rear taillights went out too! The headunit turned back on and worked fine. Also for some crazy reason my dash lights now work again!

Now I FINALLY got around to replacing a burnt fuse for the taillights, but the turn signal fuse is fine! Is there a relay or something I need to check? If so how do I do this?

Also anyone know what the deal is? I was just using the headunit a few days ago and I was moving it around a bit since the bracket/harness that is supposed to hold it in (I bought the aftermarket custom fixture since stock is double din) doesnt fit. And all of a sudden it sparked a bit, so I moved it around a little more and it made a pretty BIG spark and the player shut off. Now it wont turn back on! Im guessing I blew an internal fuse? The car radio fuse is not burnt out.

If anyone can help I greatly appreciate it! I think there is some electrical power issue here and I dont want to ruin anything any further than I might have already!

Car is a 1989 Toyota Supra 5spd N/A V6

**Also the coolant warning light flashes and sometimes stays on, although the coolant is filled to the top. Is it just a sensor going bad? The car doesnt overheat, although last month or so it did overheat at about 50mph, which im guessing was due to either an air bubble in the coolant line OR a bad mixture. It hasnt overheated or ran hot since (*knock on wood*!
