I just bought a western plow very cheap. From the research I have done I believe it is an early model 2 plug relay system. My truck came with a 3 plug isolation module system. Truck is an 06 ram if that matters. I have done a lot of reading but so far I’ve run into a lot of contradictions on my question. Probably due to my own misunderstanding and I hate to beat a dead horse but I’ll ask anyways is it possible to run this 2 plug relay plow with my 3 plug isolation harness? If not can the pump side harness be changed or do I need to change truck side?
