Just been out tidying up a few loose ends, fitted the fuel pump and the fuel filter to an ally plate on some rubber isolators to try and reduce the noise as these are bolted to the steel seat back, also took out the reverse light switch and mended this. Finally I have emailed ETB about the tacho after testing it at work and putting a scope on the ecu output. In short the tacho worked in the lab but does not in the car even though the signal from the ecu seems OK until you connect it up when the Tacho seems to drain the feed. Awaiting a reply.
