As I was prepping for a diesel upgrade, it struck me how little of the rat's nest of wiring that comes in the kit that you actually use. When I prep for a PS/3 diesel upgrade, I first prune the wiring harness to only the wires and connectors I'm actually going to use. This makes it a lot easier to dress the wiring after the wiring is complete, all those extra connectors & wires just complicate making a reasonably neat installation. Another bonus is that you have a bunch of pre-crimped connector contacts for the 1mm pitch connector. If you've actually tried crimping these contacts, you'll realize how useful those might be!
When I was finished, I was looking at the pile of wires I'm using and the pile I removed, I thought it warranted a couple of pictures.
Here's the actual wiring I'll be using for this upgrade...
And here's all the wiring that was left behind...
Just thought some might find this amusing, or even educational.
