terios limp home mode

Forum: 

How's it going? After going 4wdriving on the largest sand island in the world (Fraser Is) my beast went into limp home mode (only getting second gear) swapped over all the electrical components as I am lucky enough to have a spare car and still no joy. So with great difficulty and I checked the plug from the auto to the main loom and blah it's all full of corrosion. But how to replace without having to pull the whole box out. Thought of using a hand full of wire and those clippy dodads but as there is only a bee's dick of access and boofy boys hands would be a most painful proposition. Has anyone else been stuck with this tickly problem and how did you overcome?
