There are really 2 different wiring harnesses here. One is the FI harness, 
which you won't need at all unless you install the FI. 

The other is just the wires for the ignition and charging system, those and the 
other wires which run thru the engine compartment are probably best just 
repaired rather than replaced, because replacement is a monumental job.

A simple visual inspection would probably be adequate. I'd worry that the 
bearings might be corroded, but you'll probably just replace those anyway.

That's just a 10% increase, so I think it would be fine. You would want to 
increase the fuel pressure by 10% to compensate.
