@rocky posted:You use that switch to switch your temp gauge between coolant temperature and oil temperature!
You can use the same sender, one in the block, and one in the oil pan.
(Actually, my coolant temp sender is in the stock location in the swirl tank, because I have a “capillary” S&W gauge installed in the block).
But your setup is very cool too!

Now that’s interesting set up!!! 👍
