You may need to get past this idea that this will be "plug and play". There are threads here that speak to these issues and show you how to modify the harness for the connections you need. I am in the middle of a lot of stress and personal trouble, when the load lifts, maybe I can help. Until then, please look over threads in this part of the forum.
