    The nighthawks will work fine, it's just a pain to rewire them. If you can, pull the wires out of the old lights and then cut the new nighthawk wires and splice them into the original harness. You have a two cable system where there is one plug for switched motor power from the big relay and a second plug that combines all the lights and the control wires for the valve body. If you have the old wiring you probably have a uni-mount with one mounting hole for the old style lights. You will have to make an adapter for the two bolts on the nighthawks. What I have used for this in the past is the Ford headlight adapters. Their orignal purpose of these adapters is to move the nighthawks forward to make room for the grills that go up with the hood on the new ultra-mount plows. If you know a Western dealer nearby they probably have some kicking around. At my shop we have scads of them cus they come with the Ford truck mount kits but are only needed half the time.
