Mk3 Astra X16XEL to C20LET conversion.
Got the engine out...pulled the 1.6 loom through and removed ECU.
However, what wiring parts to i need to remove or keep.
The pic shows the sections i'm unsure of...i.e. the yellow arrowed loom goes up underneath the dash and the red highlighted parts are part of the main loom.
What's the next task in removing the loom from the car? What's the silver box?
