I was bored so I made a video.
use bog in moderation and with a spatula or you will be forever sanding, some of the rust was ground out again after realising it was there even after bog was put on so make sure if your doing this that u get all the rust out. I hope i did.
I have extended the loom by 80cm, soldered and shrinkwrapped it from the ecu side, just need to solder it onto the engine side now..
