Where to put water temp probe and oil pressure gauge on engine?
Water...down on the side of the block (middle) there is a plug (both sides)..remove plugs use one for temp gausge and put a petcock in the other for easy draining.
Oil...at the end of the 90* adapter is a plug, repalce it with a oil pressure fitting/tube.
i brazed mine in because the threads are different.
Both gauges mechanical and you can keep your factory gauges for comparison
