1990 wiring plug identification
Okay so I am beating my head and wallet up. I am having a problem with my truck almost dieing when I go into reverse and drive. Randomly has check engine light. It tends to go off when I start driving. Can someone please help me identify these plug so I can tell if I have something missing. Thanks, Kent

The first 2 are the test plugs - where you pull codes. They're supposed to have covers on them - but they don't plug in anywhere.
The other one I don't recognize right off the bat, but it looks like it belongs somewhere. One thing about that harness, there isn't any more wire length than there needs to be, so somewhere in the outer reaches of that wire should be a place for it to plug in.
You also may be able to id it by the colours of the wires - they will most probably be the only wires with that colour/stripe combo. Try finding a wiring schematic - it will have the colours on it.

I will try that. I did find this hose not connected today. It draws heavy vaccum. When the truck is running and I put my hand over it it makes the round part in the second make a weird notice. Is this hose supposed to be connected to something?
