Hey guys, so recently I completed my 2jzgte swap into my 88 NA, but at the time I was a little short on funds to put in the radiator I wanted, so incidentally I have just been running my old 7m radiator, but it wasn't doing the trick, so I finally ordered a koyo radiator, after attempting an install I noticed that next to the drain plug there is a second threaded hole with nothing in it, after doing some research I found that it's for the 1jz electric fan temp sensor, but I can't seem to find one of these anywhere, does any one know if the 2j and 1j sensors are interchangeable? Or what the thread size is since I will probably just be plugging it since my 7m didn't use one of these and neither is my 2j, and help would be much appreciated, thanks guys
