Just got my pickup back from the shop, it's a 91 pickup with a 22RE engine, I was having trouble getting it started. Guys at the shop said it was a problem with the "Mass Air Flow Sensor" (I know, I have a Volume Air Flow Sensor.) They said they could replace it with a $985 part or for $200 one of their technicians thought he could resolder something inside the VAF to fix it. Whatever they did got it working.

That day only.

I went to start it up to pull it into the garage and do some work on the wheel bearings, and it wouldn't start. Noticed I wasn't hearing the fuel pump, so started diagnosing from there. Jumped the connection in the test connector box, and the pump started fine, checked the EFI fuse and relay, and checked the "circuit opening relay" all of which were fine. Decided to open up the VAF and take a look at their soldering job, but I can't find a picture of a working VAF to base it off. I don't want to assume things and break it more...

So if anyone out there has or knows where I can find a shot of the wiring and components I would be very appreciative.

Thank you for the link, but I was actually hoping for an actual view of the components. It looks like a few things here may be bent out of place, and I'd like to see what it's supposed to look like before I start tinkering.
