I have more cables than that and just want to be super sure.
Maybe these will help explain...
The harness is full color and the extra positive and negative cables are faded. The black one is the one I am unsure about. What are the single positive and negative cables?
Here is the photo of what I have... You cannot see the single negative in the back that I am trying to figure out but it may give an idea of the rest of the wiring.
Can anyone confirm or correct the placement of that single negative cable?
