I want to add a new circuit to the driver's side fuse box in my Grand AM GT. I bought the littelfuse add-a-circuit that supports 2-10A fuses. I can add it to an existing circuit and tap a new one out of it.
Here is the problem: The littelfuse comes with one red wire that can be used for the new circuit. The car harness has two cables - white & orange. How do I connect it?
