I noticed on my B16 thats theres the temp sensor on the head and the fan switch on the thermo stat housing. Well on the stock 88'-91' Si harness they only use 1 sensor if I'm not mistaken. Everybody around my way just said I only have to use the one sensor on the head and just leave the other one alone. So is this true ? Or do you have to splice the two tegether like what some people do with 02 sensors ? Basicly is all I have to do is re-use my old connection and plug it into the head. I just want to make sure my cooling fans will kick on when they're suppose to. Thanks
