Well had the cluster for 2 weeks & had made up the loom/wires for the OBC hack so decided today I would build up the courage & fit them.
All in all it was pretty straight forward, the cluster I had found on eBay & shipped from Belgium although it was a UK 996 C4S which just so happened to have the mileage within 1k of mine so £170/$270 later I had the C4S cluater , binnacle & surround.
Went in straight forward at the same time as the OBC hack, when connected up the OBC was working fine, no need for a code.
All fitted back together, took a couple of pictures.
Whilst there I also fitted the oil pressure sensor wire ready to connect when I fit that next weekend
Cheers
Dan
