install them on the US spec cluster in my Z. The light switchs and the climate controls will then be on the opposite sides from where they are now. I assume it's just gonna be pretty simple. Simply cut the existing wires add about a foot of lenght to them and cross the harnesses to the oppisite sides they are in now. It will a small almost unnoticable difference. But I always wanted to do it cause I thought it was cool. We will see.
