I'll try to make this quick and simple. I went from a 1998 to a 2002 f150, and i removed the snowplow from one to put on the other. On the 98 the plow harness power cable was connected to the selonoid on the firewall that the battery cables are connected to. On the 98 the harness was connected to the top post and when the key was turned on I had power to the plow. On the 2002 I have constant power to the lower terminal but no power to the top terminal at anytime. Both wires come directly from the battery to the selonoid with a fusable link. My question is, if the fusable link doesn't look smoked and I have no power to the top terminal, does anyone know if there is a fuse or relay somewhere that controls this.?? I tried to make it simple, I think. any help or wire diagram would be appreciated. thanks in advanced.
