Hey Snaidy,
You can do it... rewire the car that is. Just spend a couple days (nights) studying the diagram and with simple understanding of the electics, it should not be a problem for you, espeically since you appear to be training for a future in the electics industry.
Just a quick word though, please check the wire thickness for your starter... off hand I cannot remember what the amps rating are but it was something like close to 20 amps to crank. As I drive a carbs version, I am not sure of the wiring arrangement nor the current required for a spica version. But do recheck the gage of wire you use. I just rewired mine and the smallest wire I used was 16 gage with the starter taking 12/10?? gage (need to check) and the supply to the fuse box in 10 gage. These are abit larger than what was specified by the original factory diagram but better to run "cooler" wires and more importantly have less voltage loss (which is critical in our 12v system) than a thinner wire and experience up to a 1 volt loss which will make any starter that is already marginal (or in the cold) not work at all, not to mention the potential wire overheating problem.
By the way, if the starter is kinda on the blink (nothing to do with external wire connections, a trick that I picked up from the AA or in your case the AAA (I think) is to tap the starter with a mallet. Unless it is totally conked off, a marginal starter/solenoid may be persuaded to turn just one more time. The drill is to tap it once or twice and then crank. Did that with my van for almost a whole month till I got the $$$ to change the starter out (but please if anyone should get stuck trying this out ... and it doesnt work... err please you dont know me ok!)
Alternatively, parking on a hill the whole time helps too... you might not just want to just use the clutch to jump start but once the car is rolling ever so slightly, let go of the clutch to jolt the starter and turn the key and crank the starter at the same time, the marginal starter may jolted to turn one more time. So it may not be necessary to get the stalled car up to a fair speed just to jump start it.
