The more I read in the repair manual the more confused I get. One section talks about shorting pin 34 of the connector and measuring the voltage on fuse #13 and goes on to say if the voltage is above 10 volts....... Something is telling me that the OEM system is not sending a full 12 volts to the pump at all times when it is running. I'm thinking I'm going to end up installing a double pole double throw relay in there opertated by my remote relay to keep OEM on one side of the relay & fans/pump on the other to keep things seperated. But I'm a little conserned about running a constant 12 or really 14 volts to it.
