When you lay the wiring harness back in place you should see where everything plugs in.

But not sure if it will help you much.
The CKP(crank position) sensor is down at the front of the engine so there will be a longer wire the comes from back of engine(in main harness) to the front and then that longer wire goes down the front of the engine to the CKP sensor.
I often forget to hook that one up, engine won't start without it.
There is really not a lot of wiring in the main harness
CPS(cam position sensor) wire(back of engine)
Coil pack wire
6 fuel injector wires
IAC valve wire
TPS(throttle position sensor) wire
Engine temp sender(1 wire)
ECT sensor(2 wires)
Think thats it
IAT(intake air temp) sensor was moved to MAF sensor in mid-90's
Oil pressure sender wire shouldn't be in that harness but could be at the back, and oil level sender would be with it.
