"where the wire is your standard auto multi-conductor type wiring where a 3 lead connector for example is 3 separate wires"

I'm not familiar with 3 wire bundles in automotive applications. Where would those be?

In the engine harness, your sensor signals (like TPS, MAP, MAF) are going to be twisted pairs in a factory harness, and that's what it should be and you should stick with for eliminating electromagnetic interference.

Others are going to be a single wire, like the temperature sensors.

And the O2 sensors are 4 wire, though only 2 are signal.

And sure as the world, there's a 3 wire deal somewhere but they are not the norm.

The best way to shorten wires, especially in an engine harness, is to re-pin the conductors at their connections. I've not messed with the LSx computer connectors, but for the LT1 computer connectors this is pretty easy to do (easy to add a wire too), and I expect it would be similar for the LSx stuff. For wires that don't go to the computer, I would re-pin them where possible. You can buy pins and crimp tools from a number of sources.
