So if I take box from under dash , and plug in unlocked ecu my car should defo start ? Had a fire in wiring harness on passenger floor re did all wires but immobiliser light on , hope this does trick .

you need to take it off when the engine is running

you need to take it off when the engine is running

thats only to unlock the current one. if he is fitting a new unlocked ecu that doesnt matter

So no matter what immobiliser parts are plugged in an ecu that's been professionally unlocked at bluehawke will make my car run and there's no way it can become locked again , I've been moddin \ restorin car for 2 years and its seriusly startin to look the dogs but short on money so don't wana loose 85 quid on unlocked ecu for it to go wrong , your help is much appreciated guys and making me think of becoming premium member .thanks

Leave the immobiliser unplugged when you plug it in
