300TDI Injector pump identification

I suspect I'll get an answer to this quite quickly.
My 300TDI conversion uses an injector pump with what looks like a motor housing next to the diaphram on the top of it. There is a plug with 3 wires, brown, green, black. The block is stamped 18L which means its an EDC engine yet the pump has a normal throttle cable. Is it an ERR4419 which doesnt have any wires according to the pictures I've seen or ERR4046 which apparently doesn't have a throttle cable as its fly by wire. If it is the latter which I suspect can I fine tune it as I've read on here and does it matter that its not plugged in to anything?
Can I remove the leccy bits completely? I wonder because the engine suffers diesel knock and I wondered if this is the problem.

If the bit you are talking about is round and black and sits on top of the throttle linkage, its the egr throttle position sensor and can merrily be thrown away.
You can adjust the pump timing on all the tdi engines edc or normal all done the same way

Thanks Lynall.
I'm going to do major surgery today - head gasket and water pump so whilst in there I will remove it and 'recycle it'.
