Marty, You should be fine. Adding a circuit or two should not be problem.
Newer vehicles have lots of relays on higher draw (amp) circuits such was headlights, fan, AC and etc. They do this to save money. They can run lighter gauge wire to the dash, use lighter duty switches and etc. as they are only turning on the relay. They use less copper and cheaper lighter duty parts. They only run the heavier wire between the relay and the headlights as an example.
