I have a 2006 f150 5.4 Triton, switched power source?
I have a 2006 f150 5.4 Triton.
I needed a switched power source, and found a solid red wire coming from a harness by the relays(?) in the engine compartment, on the passenger side, by the firewall.
I spliced into that wire, and it worked perfectly for about 5 miles, then the truck shut down, and now there's no power at that wire at all. (won't start)
What did I do, and can I fix it?
