How to use mechanical gauge and idiot lights?

Post #1 by falcon_master » Sun May 13, 2018 3:28 pm

Hi everyone I recently purchased this kit for 2 mechanical gauses oil pressure and water temp. How do I wire it so both my idiot lights and gauges work. Thanks

All you need to do is to use a T fitting so both of the old and new sending units can be used togeather. Good luck :thumbup: :nod:

The oil pressure gauge can be a simple T fitting on the block' oil pressure lite switch port but the Temp guage needs to be in the coolant flow. Using a T fitting on the temp port supposedly results in a 'dead 'leg' and will not read accurately. So you can use the mechanical aftermarket temp. sensor bulb in the head port instead of the electric idiot lite switch but using T and both at head port may not work read accurately. An alternate location is in the front rad hose-thermostat housing. Some housings were tapped , most had the casting that could to be tapped.

have fun

With the oil use a tee. With the water sender, mount the mechanical one in the thermostat housing.
It ain't gonna fix itself
