Use a test light to follow the red battery cable to the bulkhead connector. Not sure which relay you replaced, but that doesn't make sense if there's no power in the cab.

You can also try wiggling the wire harnesses while watching the headlights. I would first suspect a corroded splice in the red battery wire that goes to the bulkhead connector, or a corroded terminal in that connector.
