The fan I just put in I bought for my Dakota. I kept it to put it in the D50. Anyway on the Dakota I used the new fitting they have that you put in the top radiator hose. Search radiator hose adapter. I got mine in a kit with the wiring, connectors, relay and instructions. $35 On the D50 I just got the kit w/o the hose adapter because I used the thermostat housing for the temp switch. I spent the money for the thermostat housing because there is barely enough straight in the moulded hose on mine for the adapter.
