I just replaced the main ground from battery. Truck will start but I have no headlights, or dome
Light. Also the radio won't work. The blower won't turn on but shows power on the screen. Please help!
Do you
have the same problem?

Have you tested the alternator to see if it's charging? If so try to run a ground wire from the negative battery post to a good clean spot on the body.

There should be a fuse / relay box under the hood.

There are grounds all around that vehicle and you would have to do a lot of research to determine which ones apply to those components. I suggest an electrical shop for diagnosis.

They are connected to the starter with the battery cable. They are special "melt-away" fuse wires. Pull on each one and see if any stretch.

Sorry, they moved them on this truck. They are on the firewall.

I don't know what black wire you are talking about. The only other wire at the starter should be purple.
