Wiring is the least of the issues :-(
It's def. a 73 K model and it still has the exhaust end cones which are worth more than you paid for the whole bike. Side covers are available as are most other bits. I noticed that the oil tank appears to be completely empty and that means that either it was run dry (bad) or it has drained into the bottom end. That may turn out to be a blessing in disguise though if it kept the crank submersed in oil.
What are your plans for it - custom or stock, rebuild motor or just try to get it to run?
There are a few GT750 sites and the best is probably Zookie581's Sundial http://www.suzuki2strokes.com/forum/
Ian Sandy (oldjapanesebikes), one of the guys on there, has a shop manual and piles of other info on his website too for reference.
You could also look on ebay for a Clymer/Chiltons/Haynes manual.
