Why the hell would you want a BA cluster into an EF?
IMO make a better looking one with silver background, then do the blue led mod. Would look just as good.

Im pretty sure you would need the BEM, ICC, Visteon Oak ECU, and a WDS to program the cluster.

Here are some of the problems.
1) You need to program the cluster to use the Speed Sender from the Transmission and not ABS / Traction Control
2) You will need to change the speedo gear to Brown (or whatever the BA uses
3) The Data lines on the BA are Positive and Negative, (Meaning you would need BA ancilleries, and wouldnt be able to use EF/EL/AU stuff)
4) Things like Door open / Close, Temp, RPM, Fuel, and Most of the Warning lights (Seatbelt, Turn Signals, Backlighting, Airbag, ABS, Traction Control, etc, etc) all come from the Bus.
5) The Hazard switch, and dimmer and part of the cluster, and they too talk on the Bus, and dont have actuall wiring coming from them.
(I.E. on a BA, when you press the Hazard switch, it tells the ICC flash the turn signals.)

It would be very different though if someone did actually fit one to an E series or A Series Falcon !
