I was just looking through the VB catalog, and saw that they have replacement oil pressure switches....My question is where is the switch located? (I've got a 1st gen which im dropping an s4 TII motor into, i want to hook up the switch to the microtech as a warning light)

Thanks

 

There's an oil pressure sensor (not switch) for the FC's oil pressure gauge. I doubt it would work with the MicroTech.
