So this is for the experts.... I am getting ready to order a PDM setup for the car and I am trying to figure out if the PDM will be able to read a negative switch input I have setup for some temp sensors of an oil cooler, trans fan and trans pump. I wired the temp switches to ground cause I was initially going to run standard dash with relays and have them activate the relay on the negative side but cant seem to get an answer if I can have the PDM read the switch input as a ground..
thanks in advance
