Unfortunately I am not doing the work as I posted thie enquiry origionally for someone else! Sorry cant help!

Kit comes with full instructions on how to fit it its a bit more difficult than justy changing board though as the kit involves replacing the complete wiring harness and taking the room sealed cover off to get wires in

Why give Potterton anymore of your hard earned cash without trying to repair the old board first?
Remove the board and inspect all the soldered joints with a good magnifying glass. You're looking for circular hairline cracks round the joints. Pay particular attention to the joints around the diodes at the centre of the board - these were causing random lockouts on mine. Also check joints around connecting pins - these caused mine to randomly switch off the pump (with the boiler still running).
Re-solder any joints that look suspect.
Mine's run perfectly since my last repair 3 months ago (touches wood), but if it starts playing up again I'll be replacing the whole boiler with something not made by Potterton or Baxi.
