well providing your not putting led indicators on it it wouldnt make a difference what wire went where as long as you had a live and an earth going to each indicator it will work as normal as any bulb will its only the current running through it that makes the element glow.an led is a diode and current will only travel through it one way so it would matter on these type of lamps.

all black are the earth wires .the ones with the lines in them are the live .
