1y engine transplant - surplus wires

[palmtree]

hi all,
have recently purchased a 1.9 diesel 1y engine from a 96 golf and it has a few wires i am not sure what to do with
i have 3 pairs of wires

yellow/white one from the fuel solenoid and a black/white wire

red/white and black purple from little plasic box below pump

yellow/brown and green/white that comes from the centre of the 4 fuel pipes


basically- where do they all go to or are they all needed

thanks in advance

Hi, im just about to do the same, the only wire that really matters is the fuel solenoid which will connect in the same place as the old wire.
You will have another 3 wires or so, 1 will go to the inlet flange on the head nearest the oil filter, one will go on the oil filter housing and one will go on the back of the head by the bulkhead, these are all temp senders, and will also connect where they did before.
The surplus wires are possibly for the immobiliser which is not used, leave disconnected i think, someone did say to get rid of the plastic box, i dunno!

Hello, you only need the black wire that operates the fuel solenoid when you turn the key. You might then need to prime your pump to get it away. All the other wires out of the pump are not used on this "simple setup" as they were for the ECU that you do not have. Shout again good or bad news and someone will have the answer.
