Any way you can make your car "different" from the others will help.
If a thief wants a GN, they are likely to know typically what wires do what. They also study the alarm installations and the wire colors. The ones who know what they are after will do their homework.
Which is why you have to wire your car differently than every other one out there.
Similarity makes the cars easier to fix, but easier to steal.
You think that someone after a GN doesnt know about the pump connector? Or to take a spare ECM with an installed chip to bypass programs?
When I did my conversion (87 LC2 transplant) I wired in some things differently, including the pump, the ECM, and a few other select things. And using wires of all one color will confuse someone looking for a specific wire color.
You could always put a "boot" on it. Put one on each rear wheel, turn your front wheels, park nose-in, and it will be pretty hard to drag that onto a flatbed.
