When they switched to the new style interior, did they still wire the headlamps with all the power going through the switch and then back out to the lights, or did they do a proper relay setup?

While 1990 is the year they changed the dash and started using the body computer to control things, it is the only year they used the new style headlamp control module which is a blockish unit mounted at the base of the steering column. The switch signals the body computer, and the body computer controls the headlamp control module. I'm fairly certain lamp power goes through that module along with motor control.
In 1991 they eliminated the headlamp control module and used the body computer alone to control the motors, but I don't know how they wired the power to the lights.
