what does it control?

If the vehicle is fuel injected, probably the most important function is fuel supply control, among other things. If carbureted, then a large portion of it is sensors and warnings lights. Most of sensors and warnings in these trucks are vacuum operated, but pretty sure the ecu interprets the vacuum sensors "disruption" and sends out the trouble code for the OBD1 dongle

No problem. My 86 has no sensors hooked up, no emissions hooked up or anything like that. I have an aftermarket temp gauge and aftermarket oil pressure gauge and thats it. It works just fine lol
