Can anyone offer advice relating to wiring a white dial kit in to the FD3 wiring harness ?
 
Thanks

Are these the white dial faces that go over the existing gauges - the indiglo type ?

Yes.
 
Not sure of the brand, but I guess the wiring will be similar.
 
Any advice will be welcomed.
 
Thanks

I wired the power for the black box (inverter thingy) to the contact pads from one of the illumination bulbs that I took out as a result of fitting them - just soldered the wires onto the copper contact pads.
 
The advantage is that they only come on when the dash lights up - which is kind of what you want.  Dimmer function seems to work as well ;)
 
I did find there was \'miles\' too much wire on the dials - so you may want to get some of those fold over cable retainer clips that can be screw mounted - just to keep the back tidy.

Thanks for the advice Prof.
 
I can identify a thin black wire screwed to the back of the instrument cluster that must go to earth.

Also attached to the back of the instrument cluster is a small black box (obviously part of the white dial assembly) thats been attached to the back of the insrument cluster using one of the factory screws. One black [earth] one red, at the side of the screw is stated "IGN" which I assume means ignition, therefore providing a live feed to the black box when the ignition is on.
From the output side of the black box there are two wires, one yellow and one green. Where do these go ?

Also the bundle of black wires from the white dials has a number of black twin wires culmunating in a twin thin black wire to connect to the RX7 wiring. What colour wire should this connect to in the cars loom ?
