Hello everyone, 1st time I had this problem, Had the plow off for a few days and went to install it yesterday. Went to insert the large electrical plugs together and they started to bind, didn't force them together, made sure all of the pins were not bent, re-greased with electrical lube, played around for several minutes and finally snapped together. Never had this problem before. Every time I hooked the plow up in the past everything went smooth. Thanks.
