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.

Amusing yes....educational as well....so here's my question Professor- why so many extra wires in a PS3 kit? Aren't most diesels pretty much the same?

No, not really.

The ones I'm doing are pretty plain.  However, the kit provides for ditch lights, markers, number boards, MARS light, beacon, etc.  I don't install the DCC/DCS switch as this layout will never consider DCC.  For this upgrade, the Weaver engines I'm upgrading had no smoke unit, so those wires are also gone.  You always end up with a pile of wires, sometimes more, sometimes less.

That is such a good idea, I wonder who thought of that  It actually was worse with the early kits that had the real thin wire/insulation.  I told Jason that when it was being Beta'd for used.  They did move to a thicker insultation wiring and it is more manageable.  You can also support rear ditch lights if the sound file for the model has that feature.  Just add the 2 wires and patch into the common return.  G

Some guy, I forget his name.   It was a good idea, my first couple diesel upgrades looked like a bird's nest perched on the board with the bundle of wire that you ended up with!

Well, the insulation on the wire is still pretty skinny, 0.6 mm including the insulation.  I don't mind thin insulation, but they carried it too far.
