Help with son's 1990 Dodge D150 - Connectors Not Hooked Up

My son's D150 blew a fusible link this weekend so it took me a while to figure out what blew. When I took the wiring bundle apart, there were a few that were blown (no idea what they were for), so I replaced about four of them. I got it all back together, all good.

But, while working on it, there are a number of connectors not connected, and one fusible link that isn't hooked up to anything. If anyone knows what these are for, I'd love your thoughts. There isn't anything that doesn't work that he's not aware of, so not sure if they were for other options that he doesn't have.

There were a few under the dash also, but I didn't take any pics.

Thanks for any info!

The big grey one is for the early version of OBDII. A dodge diagnostic connector.

the other two I should know, but cannot think of it right off. If you can get the colors of the wires, I can look them up later, if no one else answers the question.

Sounds good, I'll take a look as soon as my son gets home from school.

Thank you!

The f-link by itself is likely the Hazard lights.....they get their own supply from the battery.

Interesting. I think they work, so wondering if someone may have rewired them at some point.

Thank you.

I believe one of the connectors is for the 4WD lamp (wiring coming from the switch on the CAD actuator on the axle).
