Not even hydraulics?
Note also this was a light vehicle; turning the wheels was quite hard unless you were moving a bit, and the brakes required a tremendous amount of force, it took me a long while to not hit contemporary '70s power brakes too hard.
What else: the windshield wipers were powered by engine vacuum, and slowed down when you accelerated (this one had a V6, so it was pretty powerful, and pretty zippy 0-30 MPH, only 3 gears forward so it lagged after that). Oh, yeah, see https://news.ycombinator.com/item?id=11919653 cars thought that era had electro-mechanical turn signals. In the case of this Jeep, the turn signal control was kludged onto the steering wheel, there was a little rubber wheel which contacted the steering wheel shaft to disengage it after you'd turned.
And not entirely reliable, 10-12 years old when I drove it, it had a towing hitch on the front, which was used more than once.
