damn...where is my DC Control module...dying to get mine in now....
I have the DC Control module connected to the high speed side, JFYR... The low speed is connected to a relay, so that I can override the DC Control and turn the fan on (it's kind of a fail safe in case the DCC ever fails, but that has yet to happen). In any case, with the override ON (fan turned on at low speed), I can barely make it to 190* temp (even in situations where I am in 4L, have the engine revving up, temp is above 85*, and there is no wind).
