There is a relay center behind the glove box, drl relay among others. There is a yellow wire carries voltage to the dimmer switch from headlamp switch. There may be a multiwire connector under dash close to steering column for circuit going in and from the steering column. If the headlamp switch is on the dash, you should be able to find the yellow wire at the connector. Turn on the lites, use testlite, see if wire is hot. For the left headlamp assembly, tan wire is low beam, lite green wire is high beam. Those wires should be at the connector also.
