There is a tiny bit of welding that's needed on my collie which I'm going to be doing soon. I've heard of ecu being fried and so on so will be disconnecting how ever many there are can any of you tell me the locations, the main ones I can think of are the main ecu and for the alarm immobiliser I've no idea where they are. I think the abs might have one and maybe one to control the 4x4 system?
