Do you have the white immo box and harness to go with the ECU? and a matching key?
Theres only one wire between the immobox and the ECU.
You do relise you need to change the inlet mani,exmani, turbo, flywheel,clutch as the AEB is a LONG type engine and not a transverse one. You would prob be better selling that on and getting an engine from an A3/Golf/Seat/Skoda etc
well if your going to scrappy then you'll find the white box has a little harness, with a bit of loom going to the coil reader, and then a few wires going to the car, these are power, ground, immo light, K-Line (diag) and immo to ECU.
To make everything work out the box, you want the white box, key, and ECU from the same car, otherwise your into reprogramming the immo.
