Yes, welcome. Glad you joined.
What part of northern Mississippi? I ask because we have a map (Bullnose Forum/Member's Map in the menu) and can add you with a city or zip.
As Bill pointed out, the EVTM is the go-to place for wiring. Far better than the wiring diagrams as it breaks the wiring down into systems and explains how each works and how to test it.
But what are the issues?
