Tony_Clarke Hello all this is my first thread and I have a 2004 astra coupe that has had the wiring removed, could anyone please tell me where the other end of the wiring leads from so I can make up a new loom. Thanks
vocky egr plug wiring goes direct to the ECU, I believe some later models never had the EGR valve this is the z22se vx220 engine wiring diagram, pins will be the same on the astra z22se https://www.speedsterclub.nl/bibliotheek/technische%20documentatie/tis/Wiring%20Diagrams/Engine%20System/Multec/Circuit%20Diagram/Engine%20Z22SE%20-%201.pdf
