fuse/relay help

Long story short. Inlaws borrowed my truck. Blew a injector line to hpop, I fixed that. Now the oil pressure guage in the dash quit but red warning light still works. I was told it may be the sensor on the hpop so I replaced that , but the oil pressure guage still doesn't work. New issue : the trailer tow harness worked fine . I had a tailgate led light bar on it but, now the harness has no power. There is plug with leds that I use but they don't light up either. I checked all the fuses and they were fine, dash and underhood. And NOW the four wheel drive switch is not lighting up on the dash nor engaging 4wd. I'm totally lost here. Is there a relay that runs

stuff.

Check Maxi Fuse 22 - 50A - Junction Box Battery Feed.
It feeds the under dash fuse panel.

My vehicle is a 01 excursion 7.3 ltr 4wd. I checked all the plugs on the tcase and all seemed plugged good.

Trailer lights are fixed , plug was unhooked on the back of factory plug. Some SOB broke the clip on the plug that goes to the tcase for 4wd . When I wiggle the wire 4wd kicks in but the vibration keeps the plug from perfect connection . Now I have to figure out how to keep that plug connected perfectly. Anybody know some back yard mechanic trick to secure this plug?
