I think it is tight in that area but it does fit. Here is an old picture with a plug in the port. The alternator burst into a ball of smoke so I am now using a ~100amp unit now. I don't use teflon tape on sensors or fittings, there are better sealers out there for that purpose. You also need to be careful with single wire type sensors like the stock units, that need to get an electrical path from the engine to work.
