147 fusebox replacement, now wont start!!
hello all this is my 1st post! ive an alfa 147 1.6 twinspark 2001 and the fuse box was corroded at 1 of the plugs! ive since replaced the fusebox which is the one in the car and now its bringing up immobiliser fault when i try to start it! ive tryed disconnecting the battery and leaving it and have erased the codes on a scan tool! i also hav noticed a wire which comes outa the loom above the fuse box and has a small grey plug on it, from there it goes over the fusebox and while i was moving it outa the way earlier the wire i think came out of some where and its not connected to anything now! is this a wire connected to the immobiliser or hav i done something else, any help is greatly appriciated as im running out of ideas
