Wiring scheme?

Put the ole 87 S10 body blazer in 4wd Monday. Oil pressure guage shot up to over the 85 lb mark and the truck died instantly.

I could tell you guys the long version but I wont.

I finally got it towed home today and went out to investigate.

BOTH sensor plugs at the oil filter were off, and the prongs were all bent downward and to the right. Well, I found the missing harness of wires...
Wrapped around the front driveshaft.

Does anyone know of some online resource that has a diagram of these wires so I can get'em back into place and get this thing going again?

Thanks in advance and Happy Holidays to all.
