Default New module to linearize the oem pressure gauge

Here it is: after I found this inexpensive pressure sender Pressure transducer or sender, 100 psi, stainless steel, for oil,fuel,air,water | eBay I done a little module to use it with the oem "fake " gauge.

It reads from zero to 100 psi, around 7 bar.
Easy to install, just screw three terminals to the back of the gauge and route three wires to the pressure sender.
If you want to add a warning light, the module is prepared to turn it off when it reaches 14.5 psi, just like an oem light
