Early cars usually don't have and don't need.

Wasn't it in the circuit for late cars with heated seats?

all the unloader relays are there for is to cut power to non essential circuits during cranking. Car will run fine without it but may take longer to crank and will be less likely to fire up with a low battery. If your car came with it keep it. I hear that some e30 never had them but I cant confirm it. All the ones I have worked on had them.
