[urq] radiator fan switch

[Jim Miller]

Hello! One quick one... or two. Looking for the right replacement part for the radiator fan switch. I have discovered most of them that I have come across are three pin. My old one is two. Just wondering if three pin will work. If so, brand of choice and who has it. Also, found a two pin but the brand name is not familiar to me. Anyone have experience with Airtex 1S4375?
Last, trying to get the tranny filler plug out and its way stubborn!!! Any BTDT advice? Any better replacements if I get it out?
Thanks a bunch!
