First off, I've looked at the topics for the GSR cluster installs, and found the wiring guides very helpful. But are these wiring diagrams the same for the JDM model as they are for the US models? If not, how do they differ? And prolly pretty stupid, but I assume you have to cut and solder all the corresponding wires? Any info/pics are appreciated. Thanks.

Oh yeah, I want to put it into a 94 dx coupe.
