I have a 1999 Dodge Ram 1500 and a Kraco K-160 Headlight Sensor. This is for turning on the headlight automatically, i have used it on previous trucks, works great! my problem is, how to wire it to turn on the headlights? I got it connected and works for the parking lights. just not sure where to connect the headlight lead into the truck to turn on lights. this unit has seaparate leads for the parking lights and headlight. i connected the headlight lead (blue) to the number 6 pin on the headlight switch, does not work. any help would be great.
