Here is the wiring digram for a '73. Would assume that the '74 would be close if not the same.

thanks tom.. it appears the tan is plugged into the acc on the fuse block and it has a sister connection for another load if needed... now i just would like to know where the resistor is located.. i have an old harness with a white wire with cloth jacket, wondering if the wire itself is the resistor... thanks.
