Battery Not Charging After Relocation
I prefer using a Ford solenoid on firewall, some prefer wiring directly to the stock solenoid on engine--either way works so 6 half dozen the other.
As stated you likely forgot to feed the alternator or distribution.
Good luck
Also, keep in mind that your neg cable should be the same size as your pos, and it too should route up to the engine compartment (just like the pos line).
