The V10 cylinder head sender send a signal to the ecm and them the ecm send serial data to the instrument cluster. The 6.0 and 5.4 and a few early V10s came with a mechanical sender that went straight to the instrument cluster. You would think it would be easier and cheaper for Ford to use the same sensor on all the trucks but oh well if I cant find the tread pitch for the sender I have I will set up a mechanical gauge.
