Does anyone know how to extract the little connectors deep within the small, rearmost plug that slots onto the ecu? Mines been playing up for a while and I've finally isolated the red wire but there's so little work room I figure the best bet is to take the connector out and attach fresh wire. Please help. I'm currently commuting in my van and that's even more knackered ?

You might be able to get a contact pin removal/resetting tool but I have no idea what it would be called. A call to ECU Testing in Notts could be worth a try.
