Box wrench with a lot of little turns for most folks. Then you could get fancy and get a 13mm six point deep socket with a slot up the side and hook it up to universal swivel adapter and an extension. Some extensions have a small swivel connection that's part of the extension. Add ratchet and presto!maxpowers said:I was reading the FAQ thread and looked at the one about getting your nuetral light to work again. My question is; how the heck do you unbolt that sensor? The engine casing is so close, I can't get a wrench around it. What did other people do?
