Injector resistor box

I am doing a mpfi swap finally. My question is, is the fuel injector resistor box the same on the hf as it is on the si. I understand they are compatible but are the identical (give the same voltage or what ever they do). Are there any other resistor boxes that are identical (in function), such as any other gens, or tegs?

Use either one, it'll work. I believe resistor box for a 91 teg will work just the same. (obd0)

The injectors on the obd-0 d series are the same so they should work fine. I believe the b series have larger ones but the box "should" work, but cant be guaranteed without one in my possession.
